golang.org/x/mod v0.37.0v0.40.0 age confidence

Fix transparency log tile verification bypass in golang.org/x/mod/sumdb/tlog

CVE-2026-56865 / GO-2026-6179

More information

Details

A malicious GOPROXY was previously capable of forging up to two sumdb tiles that allow for a requested module to bypass the GOSUMDB check and persist attacker-controlled module content to a local Go module cache.

This attack allows for a malicious GOPROXY to serve malicious module content that cannot be detected by evaluating the transparency log.

All tiles are now correctly verified against their parents.

In order to determine if you have been affected:

rm -r go.sum go.work.sum vendor/ && go mod tidy

Severity

Unknown

CVE-2026-56864 / GO-2026-6180

More information

Details

A malicious GOSUMDB was capable of serving arbitrary module content not contained within the transparency log.

This attack allows for a coordinating GOPROXY and GOSUMDB to serve a client malicious module content that cannot be detected by evaluating the transparency log.

In order to determine if you have been affected:

rm -r go.sum go.work.sum vendor/ && go mod tidy

Severity

Unknown
