The vulnerability CVE-2025-27319 in ivan82 User List (<= 1.5.1) is a reflected cross-site scripting issue caused by improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute when a user interacts with crafted input, potentially compromising user data or application behavior. The CVSS score is 7.1 (high), reflecting network attack vector, low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the context of the victim's browser, potentially resulting in theft of sensitive information, session hijacking, or manipulation of application data. The impact is rated high due to the combination of confidentiality, integrity, and availability impacts. However, no known exploits in the wild have been reported to date.

No official patch or remediation is currently available for this vulnerability. Users should monitor the vendor's advisories for updates. In the meantime, applying web application firewalls (WAF) rules to detect and block reflected XSS attempts may provide temporary mitigation. Avoiding clicking on suspicious links and ensuring user input is sanitized before rendering can reduce risk. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
