CVE-2025-2815: CWE-862 Missing Authorization in quyle91 Administrator Z
The Administrator Z plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the adminz_import_backup() function in all versions up to, and including, 2025.03.24. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site. CVE-2025-26959 is a duplicate of this issue.
AI Analysis
Technical Summary
CVE-2025-2815 is a missing authorization vulnerability (CWE-862) in the Administrator Z WordPress plugin affecting all versions up to 2025.03.24. The vulnerability arises from the lack of a capability check in the adminz_import_backup() function, allowing authenticated users with low privileges (Subscriber and above) to modify arbitrary WordPress options. This can be exploited to change the default registration role to administrator and enable user registration, resulting in privilege escalation. The vulnerability has a CVSS 3.1 score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high impact on confidentiality, integrity, and availability. No patches or vendor advisories indicating remediation are currently available, and no known exploits in the wild have been reported.
Potential Impact
An attacker with at least Subscriber-level access can exploit this vulnerability to escalate privileges to administrator by modifying WordPress site options, including the default user role and registration settings. This compromises site confidentiality, integrity, and availability by allowing unauthorized administrative control over the WordPress installation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Subscriber-level access and above to trusted users only. Consider disabling or removing the Administrator Z plugin if it is not essential. Monitor for updates from the vendor or the WordPress plugin repository for a security patch.
