CVE-2026-20800 Details
Description
Gitea's notification API does not re-validate repository access permissions when returning notification details. After a user's access to a private repository is revoked, they may still view issue and pull request titles through previously received notifications.
A vulnerability exists in Gitea's notification API, specifically in versions through 1.25.4. The issue arises because the API fails to re-validate repository access permissions when delivering notification details. As a result, users who have had their access to a private repository revoked can still see issue and pull request titles through notifications received prior to the access removal.
Users can upgrade to Gitea version 1.26.0 or later, where this issue has been addressed.
