Overview

CVE-2026-86684 is a high-severity vulnerability affecting gitea gitea. It was published on October 6, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

The Gitea push mirror API checked whether the repository owner, instead of the requesting user, may use local file system paths. On instances with `[security] IMPORT_LOCAL_PATHS = true`, a repository administrator who is not allowed to import local paths could add a push mirror to a local path on the server when the repository owner has that permission. Gitea then pushed the repository's refs into an existing Git repository at that path with the permissions of the Gitea process.

Remediation

Check the references section for vendor advisories and patches from gitea. Update gitea to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
