CVE-2025-1453Public exploitNetwork attack vector

Stored XSS via unsanitized Template content

Published Apr 24, 2025 · Updated Apr 24, 2025

Stored XSS in Category Posts Widget before 4.9.20 allows remote authenticated users to inject scripts through the Template setting. The widget stores Template content without sufficient sanitization or output escaping, then renders attacker-supplied HTML when a visitor loads the affected page. Administrator privileges and disabled unfiltered_html, as on WordPress multisite, are required; viewing the page executes the stored script in the visitor’s browser.
