- CVE-2026-89413, 18 Sep 2026
- 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. CVE record
- CVE-2026-89138, 18 Sep 2026
- 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. CVE record
- CVE-2026-90978, 18 Sep 2026
- 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.

What to do if you run Filter Gallery
If you run Filter Gallery, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
