CVE-2025-12456 affects the Centangle-Team WordPress plugin versions up to and including 1.0.0. The vulnerability arises from missing or incorrect nonce validation on a function, enabling Cross-Site Request Forgery (CWE-352) attacks where unauthenticated attackers can modify plugin settings by tricking site administrators into executing forged requests. Furthermore, insufficient input sanitization and output escaping on the cai_name_color parameter allows injection of arbitrary web scripts, resulting in stored cross-site scripting (XSS) that executes when users view the injected pages. The CVSS 3.1 base score is 6.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction needed, scope changed, and low confidentiality and integrity impacts. No official patch or remediation is currently documented.

Successful exploitation can lead to unauthorized modification of plugin settings via CSRF, potentially impacting site configuration. The stored XSS vulnerability allows injection and execution of arbitrary scripts in users' browsers, which can lead to session hijacking, defacement, or other client-side attacks. There is no indication of availability impact. No known exploits are reported in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, administrators should avoid clicking on untrusted links and consider disabling or removing the Centangle-Team plugin if possible. Monitoring for suspicious activity related to plugin settings changes and reviewing input handling for the cai_name_color parameter may help mitigate risk.
