CVE-2025-46820Public exploitNetwork attack vector

Repository compromise via token-bearing workflow artifact

Published May 6, 2025 · Updated May 6, 2025

Sensitive-information exposure in PHP.GT Dom before 4.1.8 allows remote attackers to obtain a workflow GITHUB_TOKEN from a build artifact. The ci.yml archive command packages the current checkout, including .git/config where GitHub places the token, and upload-artifact publishes that archive. Exploitation requires downloading the artifact during the short workflow run; the token then permits malicious pushes or release-tag rewrites within its assigned permissions.
