CVE-2026-72709 is fixed in spip on 1 platform, first by DEBIAN-CVE-2026-72709, released September 12, 2026. It is not reported as exploited. Patch Radar priority: Routine.
SPIP before version 4.4.18 contains a missing authorization vulnerability in sensitive actions under ecrire/action/ that allows unauthenticated attackers to invoke privileged actions by supplying only a valid CSRF nonce without any server-side permission check. Attackers can bypass template-level authorization guards through direct HTTP requests to invoke actions such as editer_auteur, enabling arbitrary account password rewrites including administrator accounts and resulting in full account takeover.
