The vulnerability CVE-2025-31085 in the xili-language plugin involves improper neutralization of input during web page generation, resulting in a reflected cross-site scripting (XSS) issue. This allows an attacker to inject malicious scripts that execute in the context of a victim's browser when they interact with a crafted link or input. The affected versions include all versions up to 2.21.2. The CVSS v3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope change, and low impacts on confidentiality, integrity, and availability. There is no information about patches or vendor advisories indicating remediation status.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the context of the affected web application, potentially allowing attackers to steal user data, hijack user sessions, or perform actions on behalf of the user. The CVSS score indicates low confidentiality, integrity, and availability impacts but a scope change, meaning the vulnerability affects components beyond the initially vulnerable component. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted input and user interactions involving the xili-language plugin. Monitor vendor channels for updates and apply patches promptly once released.
