Polylang <= 2.5 - Cross-Site Request Forgery
Strategic Overview
Vulnerability Overview
The Polylang plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.5. This is due to missing or incorrect nonce validation on the wp_insert_post_data() function. This makes it possible for unauthenticated attackers to duplicate media via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
REMEDIATION: Update to version 2.5.1, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
