AI Analysis
Technical Summary
CVE-2026-27761 affects Gitea Open Source Git Server versions up to and including 1.26.2. The issue is that repository RSS and Atom feed endpoints do not properly enforce API access token scope checks, permitting tokens lacking the necessary repository scope to retrieve private repository commit information. This represents an authorization bypass vulnerability classified under CWE-863 (Incorrect Authorization). No official remediation or patch information is currently provided by the vendor, and no known exploits are reported in the wild.
Potential Impact
The vulnerability allows unauthorized access to private repository commit data via RSS and Atom feed endpoints when using API tokens without the required repository scope. This could lead to unintended exposure of sensitive commit information. There is no indication of impact on integrity or availability, only confidentiality is affected to a limited extent.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict usage of API tokens with limited scopes on affected Gitea instances and consider disabling RSS and Atom feed endpoints for private repositories if possible.
