The vulnerability CVE-2025-52707 affects Firelight Lightbox versions up to 2.3.16 and is caused by improper neutralization of input during web page generation, leading to stored cross-site scripting (XSS). This allows an attacker with low privileges and requiring user interaction to inject malicious scripts that can compromise confidentiality, integrity, and availability of the affected system. The CVSS v3.1 base score is 6.5, reflecting a medium severity level. There is no indication of an official patch or vendor advisory at this time, and no known exploits have been observed in the wild.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to data disclosure, modification, or denial of service. The impact affects confidentiality, integrity, and availability but requires user interaction and low privileges, which limits the ease of exploitation.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should apply general best practices such as restricting user input and employing web application firewalls where possible. Monitor vendor channels for updates regarding patches or official mitigations.
