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."}],"title":"Themify Builder <= 7.7.7 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Stylesheet Write/Delete via tb_generate_on_fly AJAX Action","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b59e2773-31f0-4c19-b066-30982761bc44?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.5/classes/class-themify-builder-stylesheet.php#L160"},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.7/classes/class-themify-builder-stylesheet.php#L160"},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.7/classes/class-themify-builder-stylesheet.php#L17"},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.7/classes/class-themify-builder-stylesheet.php#L313"},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.7/classes/class-themify-builder-stylesheet.php#L69"},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.5/classes/class-themify-builder-stylesheet.php#L17"},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.5/classes/class-themify-builder-stylesheet.php#L313"},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.7.5/classes/class-themify-builder-stylesheet.php#L69"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3607906%40themify-builder&new=3607906%40themify-builder"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"PRISM"}],"timeline":[{"time":"2026-07-10T14:09:39.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-07-15T00:00:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-18T02:44:25.630245Z","id":"CVE-2026-15407","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-18T02:44:35.429Z"}}]}}
