GitHub 'Verified' Commits Can Be Rewritten Into New Hashes Without Breaking Signatures
Source: TheHackerNews

Given any signed commit, someone without the signing key can mint a second commit with the same files, author, and date, and a valid signature, GitHub still stamps "Verified." Everything a reviewer would check matches. The commit's hash does not. That matters This cybersecurity alert (GitHub 'Verified' Commits Can Be Rewritten Into New Hashes Without Breaking Signatures) reported by TheHackerNews is classified as Medium severity.
