CVE-2025-5524Network attack vector

Contributor-level stored XSS via unescaped Select tag

Published Jun 19, 2025 · Updated Apr 8, 2026

Stored XSS in the Select HTML tag in OceanWP 4.0.9 and earlier allows remote authenticated users to inject scripts into pages. The Select HTML tag handling accepts attacker-controlled markup and emits it in stored page output without sufficient sanitization or escaping. Contributor-level access is required, and the injected script runs in each visitor's browser when the affected page is opened.
