XSS in Avisverifies Verified Reviews (Avis Vérifiés)

CVE-2026-94377

The Verified Reviews (Avis Vérifiés) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'moderation' parameter in all versions up to, and including, 2.4.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The authentication bypass is possible because ntav_check_data() uses loose != comparisons for signature verification, allowing a JSON body with boolean true values for idWebsite and sign to pass all checks on any configured installation.
