NVD Description

Note: Versions mentioned in the description apply only to the upstream go1.26-openssl-doc package and not the go1.26-openssl-doc package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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
