Deeper analysis
CVE-2025-13615 is an arbitrary user password change vulnerability in the StreamTube Core plugin for WordPress, affecting versions up to and including 4.78. The issue stems from the plugin providing user-controlled access to objects, which allows attackers to bypass authorization checks and access system resources. It is associated with CWE-639 (Authorization Bypass Through User-Controlled Key) and carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its high impact on confidentiality, integrity, and availability.
Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no user interaction. Successful exploitation enables changing passwords for any user, including administrators, potentially resulting in full account takeover. Note that exploitation requires the 'registration password fields' option to be enabled in the theme settings.
