Impact
A repository's external issue tracker regular expression containing alternating capture groups could produce invalid slice indexes when Gitea rendered issue references, causing a runtime panic that terminated the Gitea process. A user who can edit a repository's external issue tracker settings could make any later rendering of matching content, such as viewing a README, crash the instance for all users.
