Gogs is an open source self-hosted Git service. In versions of gogs prior to 0.12.9 DisplayName
does not filter characters input from users, which leads to an XSS vulnerability when directly displayed in the issue list. This issue has been resolved in commit 155cae1d which sanitizes DisplayName
prior to display to the user. All users of gogs are advised to upgrade. Users unable to upgrade should check their users' display names for malicious characters.
