CVE-2022-23738Network attack vector

Private repository disclosure via incomplete cache keys

Published Nov 1, 2022 · Updated May 6, 2025

Improper cache-key generation in GitHub Enterprise Server affected releases allows remote authenticated users to read private repository files. The published record does not identify the cache component or which request attributes the key fails to incorporate, but states that private files are served through a public repository. Exploitation requires instance access, permission to create a public repository, and a site administrator who visits a crafted URL.
