CVE-2025-71244Network attack vector

External redirection via AJAX login URL

Published Feb 19, 2026 · Updated Feb 19, 2026

Open redirect in SPIP 4.3.0 through 4.3.8 and 4.4.0 through 4.4.4 allows remote attackers to redirect users via crafted login URLs. Published materials identify the AJAX-mode login form but do not disclose which parameter or validation error accepts an external destination. Exposure requires an overridden AJAX login page and a victim who follows the crafted URL and completes login, after which the browser leaves the site.
