The vulnerability CVE-2025-58784 affects arisoft ARI Fancy Lightbox versions up to 1.4.0 and is classified as a stored cross-site scripting (XSS) issue. It results from improper input neutralization during web page generation, enabling attackers with low privileges to inject malicious scripts that execute when other users view the affected pages. This can lead to partial compromise of confidentiality, integrity, and availability of the affected system. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, required privileges, user interaction, and a scope change. No patch or vendor advisory is currently provided, and no known exploits have been reported.

Successful exploitation allows an attacker with low privileges to inject persistent malicious scripts that execute in the browsers of other users, potentially leading to partial disclosure of information, modification of data, or disruption of service. The vulnerability affects confidentiality, integrity, and availability to a limited extent as indicated by the CVSS vector. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting privileges of users who can input data displayed by ARI Fancy Lightbox and apply web application firewall (WAF) rules to detect and block XSS payloads related to this plugin. Monitor vendor channels for updates and apply patches promptly once available.
