CVE-2023-26054Network attack vector

Credential disclosure via unredacted Git URL metadata

Published Mar 6, 2023 · Updated Feb 25, 2025

Information exposure in Moby Project BuildKit 0.10.0 through 0.11.3 allows attackers to read Git credentials from build metadata. The provenance predicate copied userinfo from context and vcs:source Git URLs into attestations or BuildInfo instead of redacting it. Exposure requires credentials embedded in a Git URL or supplied as VCS hints and access to the resulting provenance attestation or BuildInfo.
