Gitea's notification API does not re-validate repository access permissions when returning notification details.
MEDIUM 6.5EPSS 0.38%
Does this matter?
Lower severity and a low EPSS score (0.38%). Track it; it rarely justifies an emergency change on its own.
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.
