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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions
