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."}],"title":"Pubjet | پاب‌جت <= 5.4.8 - Authenticated (Subscriber+) Privilege Escalation to 'check-token' AJAX Action","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/0391145a-2707-4639-80d0-a8a98512ef66?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/Ajax.php#L643"},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/Ajax.php#L631"},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/Ajax.php#L26"},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/RestApi.php#L374"},{"url":"https://plugins.trac.wordpress.org/browser/pubjet/tags/5.4.8/includes/RestApi.php#L363"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L","baseScore":7.6,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Wordfence PRISM"}],"timeline":[{"time":"2026-11-05T22:00:19.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-11-06T17:32:50.839014Z","id":"CVE-2026-103479","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":"2026-11-06T17:33:03.308Z"}}]}}
