{"id":"CVE-2026-103479","published":"2026-11-06T12:17:15.440","lastModified":"2026-11-06T18:17:38.390","description":"The Pubjet | پاب‌جت plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 5.4.8. This is due to the `checkToken()` AJAX handler — registered under `wp_ajax_pubjet-check-token` — performing no capability check and no nonce verification before unconditionally writing the attacker-supplied `token` GET parameter directly into the site-wide `pubjet_settings` option via `pubjet_update_setting()`, prior to any remote validation. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the plugin's stored REST API credential with an attacker-chosen value, immediately elevating their effective privileges to those of an authorized Pubjet API client and enabling them to invoke otherwise-restricted endpoints — `createReportage`, `updateReportage`, `deleteReportage`, `toggleCopyright`, and `createBacklink` — to create, modify, and delete arbitrary reportage posts and manipulate plugin state that Subscribers cannot normally access. The privilege escalation is self-reinforcing: because `RestApi::isTokenValid()` authenticates solely by comparing the incoming `Authorization` header against the value returned by `pubjet_token()`, which reads from the same option the unprotected handler writes to, the attacker-planted token is trusted as legitimate on all subsequent requests.","cvssScore":7.6,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L","cwes":["CWE-269"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/Ajax.php#L26","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/Ajax.php#L631","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/Ajax.php#L643","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/RestApi.php#L363","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/RestApi.php#L374","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/0391145a-2707-4639-80d0-a8a98512ef66?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
