CVE-2023-23765Network attack vector

Commit smuggling via incorrect reopened pull-request diff

Published Aug 30, 2023 · Updated Sep 27, 2024

Incorrect comparison in GitHub Enterprise Server allows remote authenticated users to smuggle commits through reopened pull requests. The reopened-pull-request diff performs an incorrect comparison, but GitHub has not disclosed the compared values or implementation locus. Repository write access and a reviewer viewing the reopened pull request are required; the misleading diff can conceal source-branch commits during review.
