CVE, Research URL: CVE-2025-11734
Home page URL: Security reports for Broken Link Checker by AIOSEO – Easily Fix/Monitor Internal and External links
Application: Broken Link Checker by AIOSEO – Easily Fix/Monitor Internal and External links
Date: Nov 18, 2025
Research Description: The Broken Link Checker by AIOSEO – Easily Fix/Monitor Internal and External links plugin for WordPress is vulnerable to unauthorized post modification due to missing authorization in all versions up to, and including, 1.2.5. This is due to the plugin registering a REST API endpoint that only checks for a broad capability (aioseo_blc_broken_links_page) that is granted to contributor level users, without verifying the user's permission to perform actions on the specific post being targeted. This makes it possible for authenticated attackers, with contributor level access and above, to trash arbitrary posts via the DELETE /wp-json/aioseoBrokenLinkChecker/v1/post endpoint.
Affected versions: max 1.2.6.
Status: vulnerable
