Improper authorization in Gogs 0.11.91 allows remote authenticated users to change another account’s primary email via web settings. MakeEmailPrimary accepts an email record by ID but, before the fix, does not verify that its UID matches the requesting user, allowing a user to promote another user’s verified address.
