The vulnerability CVE-2025-23817 affects the MHR-Custom-Anti-Copy plugin by mahadirz, allowing attackers to exploit a CSRF flaw that results in Stored XSS. This means that an attacker can trick a user into submitting a malicious request that the application processes, leading to persistent script injection. The affected versions include all releases up to and including version 2.0. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to Stored XSS, which may allow attackers to execute arbitrary scripts in the context of the victim's browser. This can result in theft of sensitive information, session hijacking, or other malicious actions. The CSRF aspect means that attackers can induce authenticated users to perform unwanted actions without their consent. The overall impact affects confidentiality, integrity, and availability to a limited extent as indicated by the CVSS vector.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or fix information is provided, users should monitor the vendor's communications for updates. Until a fix is available, consider implementing CSRF protections such as verifying anti-CSRF tokens on sensitive requests and applying web application firewall (WAF) rules to detect and block suspicious requests related to this plugin.
