CVE-2026-55984: Gitea: Null Pointer Dereference in AddTime API Causes Authenticated Denial of Service

July 21, 2026

The AddTime API handler continues execution after an error returned by GetUserByName().

When a repository administrator specifies a non-existent user name, an error response is generated but execution does not stop. Subsequent code dereferences a nil user pointer, resulting in a runtime panic.
