AI Analysis
Technical Summary
CVE-2026-29965 identifies a Cross Site Scripting (CWE-79) vulnerability in HSC MailInspector 5.3.3-7 specifically at the /police/WarningUrlPage.php endpoint. The vulnerability is due to insufficient sanitization of user-supplied input that can include alternate or obfuscated JavaScript syntax, enabling script injection. The CVSS 3.1 base score is 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity with no impact on availability. No patch or official fix information is provided, and the product is not a cloud service.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to limited confidentiality and integrity impacts such as session hijacking or content manipulation. The vulnerability does not affect availability. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting access to the vulnerable endpoint or applying web application firewall (WAF) rules to detect and block suspicious input patterns. Avoid relying on user input without proper sanitization in this endpoint.
