CyberRota Analysis

AI-Generated

The Filter Gallery plugin for WordPress is susceptible to an authorization bypass vulnerability, allowing authenticated attackers with subscriber-level access or higher to delete arbitrary Filter Gallery records by manipulating gallery IDs. This flaw arises from inadequate verification of user permissions, specifically through a nonce bypass that allows the omission of the nonce POST field. WordPress site administrators using this plugin should prioritize immediate updates to version 1.1.5 or later to mitigate potential data loss and unauthorized actions.

Original NVD Description

The Filter Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.4. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete any arbitrary Filter Gallery records — including all associated filters, image mappings, settings, and details options — by supplying attacker-controlled gallery IDs. The nonce bypass requires omitting the nonce POST field entirely rather than submitting an invalid value, as a present-but-invalid nonce is correctly rejected.
