Contributor-level stored XSS via unsanitized input
Published Oct 22, 2025 · Updated Oct 22, 2025
Stored XSS in WPClever WPC Countdown Timer for WooCommerce 3.1.4 and earlier allows remote authenticated users to inject scripts. The plugin stores user-controlled page content without sufficient sanitization and renders it without adequate output escaping; published sources do not identify the affected parameter or function. Contributor-level access is required, and the payload executes when another user visits an injected page, allowing script execution in that visitor's browser.
