An Ubuntu-specific patch to AccountsService before 23.13.9-8ubuntu7 only partially drops privileges before launching language helper scripts. It changes the effective UID/GID to the target user but leaves the real UID as 0 (root). A shell spawned by a helper script inherits ruid=0 and may reset its effective UID to root, enabling local privilege escalation.
