CVE-2026-26223 · SPIP < 4.4.8 Cross-Site Scripting via Iframe Tags in Private Area

This page contains facts from public vulnerability sources. Check the original advisory before updating.

SPIP before 4.4.8 allows cross-site scripting (XSS) in the private area via malicious iframe tags. The application does not properly sandbox or escape iframe content in the back-office, allowing an attacker to inject and execute malicious scripts. The fix adds a sandbox attribute to iframe tags in the private area. This vulnerability is not mitigated by the SPIP security screen.
