CVE-2025-13031Public exploitNetwork attack vector

Stored XSS via unescaped campaign settings

Published Dec 9, 2025 · Updated Dec 12, 2025

Stored XSS in WPeMatico RSS Feed Fetcher before 2.8.13 allows remote authenticated users to execute scripts via campaign settings. The campaign editor stores custom post templates and the first two Rewrite Options text fields without sanitizing or escaping them before rendering their values. Contributor access is sufficient; execution occurs on submission and again when a super administrator opens the campaign, while Rewrite Options require that feature to be enabled.
