What happened

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.

About this data

This record was ingested from a data source. Retrieved: Nov 6, 2026, 13:50 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
