CVE-2026-27761: CWE-863 in Gitea Gitea Open Source Git Server
Gitea versions up to and including 1.26.2 have a vulnerability where repository RSS and Atom feed endpoints bypass API access token scope checks. This allows tokens without the required repository scope to access private repository commit data via these feeds. The issue is classified as CWE-863 (Incorrect Authorization).
AI Analysis
Technical Summary
CVE-2026-27761 affects Gitea Open Source Git Server versions up to 1.26.2. The vulnerability allows repository RSS and Atom feed endpoints to bypass API access token scope checks, exposing private repository commit data to tokens that do not have the necessary repository scope. This improper authorization flaw (CWE-863) could lead to unauthorized read access to private repository information. The CVSS 3.1 base score is 4.3, indicating a medium severity level with network attack vector, low attack complexity, and low privileges required.
Potential Impact
An attacker or user with an API token lacking the required repository scope can access private repository commit data through the RSS and Atom feed endpoints. This leads to unauthorized disclosure of private repository information but does not affect integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict API token permissions carefully and avoid using tokens with insufficient scope for accessing repository feeds. Monitor vendor communications for updates on patches or official fixes.
