CVE-2025-71240Network attack vector

Stored XSS via unchecked JavaScript in code tags

Published Feb 19, 2026 · Updated Feb 19, 2026

Cross-site scripting in SPIP 4.2.0 through 4.2.14 allows remote authenticated users to execute scripts via crafted code tags. The HTML code-tag processing path accepts JavaScript-bearing content without applying the JavaScript check needed to neutralize executable markup. An authenticated content author must save the crafted markup and a victim must view the rendered content, exposing the victim session to script-driven data access or actions.
