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 or delete the generated CSS stylesheet file of arbitrary posts, including private and draft posts owned by other users, and modify plugin-scoped font options. The required CSRF nonce (tf_nonce) is emitted on public front-end builder pages via wp_localize_script, making it trivially obtainable by any authenticated user visiting such a page.","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:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.5/classes/class-themify-builder-stylesheet.php#L160","https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.5/classes/class-themify-builder-stylesheet.php#L17","https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.5/classes/class-themify-builder-stylesheet.php#L313","https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.5/classes/class-themify-builder-stylesheet.php#L69","https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.7/classes/class-themify-builder-stylesheet.php#L160"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-15407","score":0.00473,"percentile":0.40884,"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).
