The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-15 (Information Output Filtering).

Deeper analysis

CVE-2025-14937 is a stored cross-site scripting (XSS) vulnerability, classified under CWE-79, in the Frontend Admin by DynamiApps plugin for WordPress. It affects all versions up to and including 3.28.23. The issue stems from insufficient input sanitization and output escaping in the 'acff' parameter handled by the 'frontend_admin/forms/update_field' AJAX action.

Unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. By injecting arbitrary web scripts via the vulnerable endpoint, attackers can have those scripts stored on pages and executed in users' browsers whenever those pages are accessed, potentially leading to low confidentiality and integrity impacts with a changed scope, as reflected in the CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N).
