CVE-2024-7954Known exploitationPublic exploitNetwork attack vector

Unauthenticated PHP execution via preview eval

Published Aug 23, 2024 · Updated Nov 22, 2025

Code injection in SPIP before 4.1.16, 4.2.13, and 4.3.0-alpha2 allows remote attackers to execute arbitrary PHP. The unauthenticated porte_plume_previsu action passes crafted link markup through preview processing until traitements_previsu_php_modeles_eval decodes embedded PHP and executes it with eval. Public-network reachability of the preview action is sufficient, and successful exploitation runs code with the privileges of the SPIP service account.
