v5.18.0→v5.19.0go-git's improper parsing of specially crafted objects may lead to inconsistent interpretation compared to upstream Git
CVE-2026-45022 / GHSA-389r-gv7p-r3rp
More information
Details
Impact
go-gitmay parse malformed Git objects in a way that differs from upstream Git. Whencommitortagobjects contain ambiguous or malformed headers,go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object.Additionally,
go-git’s commit signing and verification logic operates over commit data reconstructed fromgo-git’s parsed representation rather than the original raw object bytes. As a result,go-gitmay sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository.This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed.
Patches
Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported
go-gitversion.Credit
