CVE-2026-27783: CWE-862 in Gitea Gitea Open Source Git Server
Gitea versions up to and including 1.26.1 have a vulnerability where repository-unit authorization is not enforced on issue-template API endpoints. This allows users with limited privileges to potentially access or interact with issue templates without proper authorization. The vulnerability is classified as CWE-862 (Missing Authorization).
AI Analysis
Technical Summary
CVE-2026-27783 is a vulnerability in Gitea Open Source Git Server affecting versions up to and including 1.26.1. The issue arises because the software does not enforce repository-unit authorization checks on the issue-template API endpoints. This means that users with limited privileges (PR:L) can access these endpoints over the network (AV:N) without user interaction (UI:N), potentially leading to unauthorized information disclosure (C:L) but no impact on integrity or availability. The CVSS v3.1 base score is 4.3, indicating a medium severity vulnerability.
Potential Impact
The vulnerability allows unauthorized access to issue-template API endpoints, potentially exposing information related to issue templates. The impact is limited to confidentiality loss; there is no impact on integrity or availability. Exploitation requires low privileges and network access but no user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch is indicated in the available data, users should monitor the Gitea project for updates addressing this authorization issue. Until a fix is available, restrict access to the affected API endpoints where possible and review user privileges to minimize exposure.
