This vulnerability (CVE-2025-22365) in Eric McNiece EMC2 Alert Boxes is a stored cross-site scripting (CWE-79) issue caused by improper input neutralization during web page generation. It affects versions through 1.3 and allows attackers to inject malicious scripts that persist and execute in the context of users' browsers. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring low privileges and user interaction, with a scope change and partial impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of affected users, potentially leading to data disclosure, modification, or disruption of service. The impact is rated medium based on the CVSS score and vector, reflecting limited but meaningful risk to confidentiality, integrity, and availability.

No official patch or remediation is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
