DescriptionThe 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.
