Vulnerability from github – Published: 2026-02-19 18:31 – Updated: 2026-02-19 18:31

Details

SPIP before 4.4.8 allows Cross-Site Scripting (XSS) in the public area for certain edge-case usage patterns. The echapper_html_suspect() function does not adequately detect all forms of malicious content, permitting an attacker to inject scripts that execute in a visitor's browser. This vulnerability is not mitigated by the SPIP security screen.

Severity ?

4.7 (Medium)
