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.

Executive Summary

This vulnerability exists in the Broken Link Checker plugin by AIOSEO for WordPress, where a REST API endpoint lacks proper authorization checks. Although it requires a broad capability granted to contributor-level users, it does not verify if the user has permission to modify the specific post targeted. As a result, authenticated users with contributor-level access or higher can delete arbitrary posts via the plugin's REST API.

Mitigation Strategies

To mitigate this vulnerability, immediately update the Broken Link Checker by AIOSEO plugin to a version later than 1.2.5 where the authorization issue is fixed. If an update is not yet available, restrict contributor level user permissions or disable the plugin until a patch is released to prevent unauthorized post modifications via the REST API endpoint.

Impact Analysis

An attacker with contributor-level access or higher can exploit this vulnerability to trash arbitrary posts on the WordPress site. This could lead to loss of content, disruption of site functionality, and potential damage to the site's integrity and user trust.
