description

Gitea is affected when its repository route is requested for an individual user. A remote unauthenticated attacker can repeatedly cause server panics and HTTP 500 responses, potentially impairing service availability; no special configuration is needed.

mitigation

Restrict unauthenticated access to the affected repository route through a reverse proxy or equivalent control, and monitor for repeated malformed route requests. Apply Gitea’s vendor update when a fixed release is identified.

fixed in 28.2.0
