Description

This module exploits an unauthenticated PHP code injection in the SPIP
Saisies plugin (CVE-2025-71243). The _anciennes_valeurs form parameter is
interpolated unsanitized into a hidden field rendered with
interdire_scripts=false, allowing direct PHP code execution via template
eval.

Exploitation requires a publicly accessible page containing a
saisies-powered form, most commonly created with the Formidable plugin.
Use the FORM_PAGE option to specify a known form page, or set it to
'crawl' to automatically discover one by following internal links from
the SPIP sitemap.

Versions 5.4.0 through 5.11.0 of the saisies plugin are affected.
