This vulnerability (CVE-2025-5254) in Kron PAM is due to improper input sanitization leading to stored Cross-site Scripting (CWE-79). It affects versions before 3.7 and allows an attacker with high privileges to inject malicious scripts that are stored and later executed in the context of other users. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, unchanged scope, and high impact on confidentiality and integrity. No patch or official fix information is available at this time.

Successful exploitation can lead to execution of malicious scripts in the context of privileged users, potentially compromising confidentiality and integrity of the system. Availability is not impacted. The attack requires an attacker to have high privileges and for a user to interact with the malicious content.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit exposure by restricting high-privilege user access and exercising caution with user-generated content. Monitor vendor communications for updates on patches or official mitigations.
