The WP Custom Admin Interface plugin for WordPress, developed by Northern Beaches Websites, contains a DOM-based Cross-site Scripting vulnerability identified as CVE-2026-32521. This vulnerability arises from improper neutralization of input during web page generation, allowing an attacker to inject malicious scripts into the web interface. The affected versions include all versions up to 7.42. The CVSS score is 6.5 (medium severity), with an attack vector of network, low attack complexity, requiring privileges and user interaction, and impacts on confidentiality, integrity, and availability at a low level. No known exploits are reported in the wild, and no patch or vendor advisory is currently provided.

Successful exploitation of this vulnerability could allow an attacker with some privileges and requiring user interaction to execute arbitrary scripts in the context of the affected web interface. This may lead to limited confidentiality, integrity, and availability impacts such as session hijacking, defacement, or other malicious actions within the scope of the plugin's privileges. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, users should limit privileges to trusted users and avoid interacting with untrusted content in the affected plugin interface.
