Published: 27 November 2025
Summary
CVE-2025-13675 is a critical-severity Improper Privilege Management (CWE-269) vulnerability in Themeforest (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 40.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-2 (Account Management) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2025-13675 is a privilege escalation vulnerability in the Tiger theme for WordPress, affecting all versions up to and including 101.2.1. The flaw arises in the 'paypal-submit.php' file, which does not enforce restrictions on the user roles that can be assigned during registration, allowing arbitrary role specification. It is classified under CWE-269 (Improper Privilege Management) 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), reflecting its critical severity.
Unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. By supplying the 'administrator' role during the registration process, they can gain full administrator access to the affected WordPress site, enabling complete control over content, users, plugins, and themes.
Advisories and additional details are provided by Wordfence in their threat intelligence report and on the Tiger theme's product page at ThemeForest. Security practitioners should consult these sources for patch availability or workaround recommendations, published as of 2025-11-27.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-2 requires management of account creation and privilege assignment processes, directly preventing improper role specification like 'administrator' during unauthenticated registration in the paypal-submit.php file.
SI-10 mandates validation of information inputs such as the user role parameter, blocking arbitrary privilege escalation by rejecting unauthorized 'administrator' roles in the registration script.
AC-6 enforces least privilege by restricting accounts to only necessary permissions, mitigating the impact of any successful improper admin role assignment during registration.
