{"cve":"CVE-2026-89413","nvd":{"published":"2026-09-18T07:16:51.337","modified":"2026-09-18T15:17:17.990","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/filter-gallery/tags/1.1.4/filter-gallery.php#L1099","https://plugins.trac.wordpress.org/browser/filter-gallery/tags/1.1.4/filter-gallery.php#L1112","https://plugins.trac.wordpress.org/browser/filter-gallery/tags/1.1.4/filter-gallery.php#L1131","https://plugins.trac.wordpress.org/changeset?reponame=&old=3695415%40filter-gallery&new=3695415%40filter-gallery","https://www.wordfence.com/threat-intel/vulnerabilities/id/0487c6dd-7453-4473-9a13-6b699623f8a9?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-89413","score":0.00536,"percentile":0.45235,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
