CVE-2026-3582Network attack vector

Repository search disclosure via missing PAT scope check

Published Mar 10, 2026 · Updated Mar 10, 2026

Incorrect authorization in GitHub Enterprise Server allows remote authenticated users to retrieve private issue and commit search results. The /search/commits and /search/issues REST endpoints honor the repo:OWNER/REPO qualifier without enforcing the classic PAT repo scope. Exploitation requires existing repository access through organization membership or collaboration; affected releases are 3.16.0 through 3.16.14, 3.17.0 through 3.17.11, 3.18.0 through 3.18.5, and 3.19.0 through 3.19.2.
