CVE-2026-13764Masterstudy - Education WordPress Theme <= 4.8.151 - Missing Authorization to Authenticated (Subscriber+) Privilege Escalation

Açıklama

The Masterstudy - Education WordPress Theme theme for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.8.151. This is due to missing authorization and nonce validation on the `masterstudy_ms_stm_set_discard_transient` AJAX action. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to Administrator by setting the `stm_developer_access_token` transient and using the developer access auto-login flow to obtain administrator session cookies.

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.
