CyberRota Analysis

AI-Generated

The Filter Gallery plugin for WordPress prior to version 1.1.5 is vulnerable due to insufficient nonce verification and lack of capability checks in its AJAX handlers. This allows low-privileged users to overwrite content of arbitrary posts and delete stored gallery options, potentially leading to unauthorized content manipulation and loss of data. WordPress site administrators using this plugin should prioritize updating to version 1.1.5 or later to mitigate these risks.

Original NVD Description

The Filter Gallery WordPress plugin before 1.1.5 does not verify the nonce on several of its AJAX handlers when the nonce field is omitted, and applies no capability check, allowing low-privileged users to overwrite the content of arbitrary posts and delete the Filter Gallery WordPress plugin before 1.1.5's stored gallery options.
