Vulnerability in Spip
CVE-2026-72710
SPIP before 4.4.18 contains a mass assignment vulnerability in the editer_objet action that allows unauthenticated attackers to write arbitrary rows to any SQL table lacking a champs_editables allowlist by supplying an attacker-controlled arg parameter resolving to internal database tables. Attackers can insert a malicious row into the spip_jobs queue with a controlled PHP function and arguments, which is then dynamically executed when the cron processes the queue, resulting in remote code execution.
