CVE-2026-107686: Gitea reactions accepted on locked issues and comments
Published Oct 18, 2026
·Updated
The Gitea web handlers for adding and removing reactions on issues and comments did not refuse locked issues for users without write access, although the API did. A signed-in user who could read an issue could therefore add or remove reactions on a locked issue and its comments, bypassing the interaction restriction of the lock. Only reactions were affected; no content could be changed.

Frequently Asked Questions
1
Are anonymous users affected by this behavior?

2
Are reaction changes made through the API affected?
No. The API already refused reactions on locked issues for users without write access; the issue was limited to the web handlers.
