File Browser has risk of HTTP Request/Response smuggling through vulnerable dependency

Critical severity GitHub Reviewed Published Nov 13, 2025 in filebrowser/filebrowser • Updated Nov 13, 2025

Package

gomod github.com/filebrowser/filebrowser/v2 (Go)

Affected versions

<= 2.45.1

Patched versions

2.45.2

Description

The standard library net/http package dependency used by File Browser improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. I can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.

See https://nvd.nist.gov/vuln/detail/CVE-2025-22871 for more details.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
