Executive Summary

CVE-2026-59765 is a Server-Side Request Forgery (SSRF) vulnerability in Gitea that allows attackers to bypass hostmatcher protections and read internal files or cloud metadata. It occurs because three code paths use raw http.Get() calls without proper IP validation, enabling SSRF attacks against internal services and local file reads via file:// scheme.

Impact Analysis

Attackers with migration permissions or OAuth access could exploit this to steal cloud metadata like AWS IMDSv1 credentials or GCP tokens. They could also read sensitive local files such as /etc/gitea/app.ini, which contains database credentials and secrets.

Mitigation Strategies

Update Gitea to the latest patched version to address the SSRF vulnerability in migration asset downloads. Review and restrict migration permissions to only necessary admin/org owners. Inspect OAuth configurations for malicious URLs and remove any unauthorized entries. Monitor network traffic for unusual requests to internal services or cloud metadata endpoints.
