Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in FirelightWP Firelight Lightbox allows Stored XSS. This issue affects Firelight Lightbox: from n/a through 2.3.16.
AnalysisAI
Stored cross-site scripting in Firelight Lightbox WordPress plugin up to version 2.3.16 allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These scripts execute when other users view the affected pages, potentially leading to session hijacking or defacement. No public exploit or active exploitation has been identified at this time.
Technical ContextAI
The vulnerability is a stored cross-site scripting (XSS) flaw in the Firelight Lightbox plugin for WordPress. The plugin provides lightbox functionality for images and galleries. The issue arises from improper neutralization of user-supplied input during web page generation (CWE-79). Attackers with low-privileged accounts (e.g., contributor) can inject malicious scripts that are stored on the server and executed in the browsers of other users, including administrators. The CVSS vector indicates a network attack vector, low attack complexity, low privileges required, and user interaction required, with a scope change to the vulnerable system.
RemediationAI
Update the Firelight Lightbox plugin to version 2.3.17 or later, which contains the fix. The vendor advisory from Patchstack provides details. As a workaround, restrict the ability to create or edit posts to trusted users only, and consider using a web application firewall (WAF) to filter XSS payloads. Note that disabling the plugin may affect lightbox functionality.
