CVE-2024-50460 describes a stored cross-site scripting vulnerability in Firelight Lightbox (easy-fancybox) versions up to 2.3.3. The issue is caused by improper neutralization of input during web page generation, which allows attackers with high privileges to inject malicious scripts that are stored and later executed in users' browsers. The vulnerability has a CVSS 3.1 base score of 5.9, reflecting medium severity with network attack vector, low attack complexity, required privileges, and user interaction. There is no vendor advisory or patch information available at this time, and no known active exploitation has been reported.

Successful exploitation of this vulnerability could allow an attacker with high privileges to inject and store malicious scripts that execute in the context of other users' browsers. This can lead to limited confidentiality, integrity, and availability impacts such as theft of sensitive information, session hijacking, or disruption of service. However, exploitation requires user interaction and elevated privileges, which reduces the overall risk.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should limit privileges to trusted users and apply standard XSS mitigations where possible. Monitor vendor channels for updates regarding patches or official workarounds.
