The vulnerability CVE-2025-31440 in the Strategy11 Team Terms of Use plugin (versions up to 2.0) is a Cross-Site Request Forgery (CSRF) issue that enables Stored Cross-Site Scripting (XSS). This means an attacker can trick an authenticated user into submitting a request that stores malicious script code, which can then be executed in the context of the victim's browser. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

Successful exploitation can lead to stored XSS attacks, allowing an attacker to execute arbitrary scripts in the context of the victim's browser. This can result in limited compromise of confidentiality, integrity, and availability of the affected system or user data. The vulnerability requires user interaction and can be exploited remotely without authentication.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or restricting the use of the affected Terms of Use plugin version 2.0 or earlier. Implementing anti-CSRF tokens and input validation may help mitigate the risk, but official vendor guidance should be followed once available.
