Summary
The Verified Reviews (Avis Vérifiés) plugin for WordPress, in all versions up to and including 2.4.6, does not sanitize input or escape output for the 'moderation' parameter, a CWE-79 flaw. An unauthenticated attacker can store arbitrary web scripts that run in a user's browser when that user opens an injected page. The attacker can also get past signature checks because loose comparisons accept boolean true values for idWebsite and sign.

Description from the CNA
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.
