CVE-2022-23979Network attack vector

Authenticated stored XSS

Published Jan 28, 2022 · Updated Apr 28, 2026

Cross-site scripting in Ultimate Reviews for WordPress 3.0.15 and earlier allows remote authenticated users to store script content. Public advisories do not identify the plugin file, hook, or parameter responsible for insufficient sanitization and output encoding. Admin-level authentication and a victim's interaction with rendered review content are required; successful exploitation executes attacker-controlled script in a user's browser, affecting confidentiality and integrity.
