The vulnerability identified as CVE-2026-25351 affects skygroup's MyMedi product, specifically versions before 1.7.7. It is a reflected cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows attackers to inject and execute arbitrary scripts in users' browsers when they visit a crafted URL or page. The CVSS v3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No patch or official remediation details are provided in the available data.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of a user's browser session, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability as indicated by the CVSS vector. The reflected nature means the attack requires user interaction (e.g., clicking a malicious link). There are no known exploits 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 available, users should exercise caution with untrusted input and URLs. Implementing web application firewall (WAF) rules to detect and block reflected XSS attempts may provide temporary mitigation. Monitor vendor communications for updates on patches or official fixes.
