GHSA-38VH-9C8V-RMGW

Vulnerability from github – Published: 2026-09-18 09:31 – Updated: 2026-09-18 09:31

Details

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 overwrite the title and content of arbitrary WordPress posts, write the wp_attachment_image_alt meta key on arbitrary posts, and create or overwrite arbitrary ufg_gallery* options.

Severity

4.3 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
