CVE-2025-71177 · Severity: medium · CVSS 5.4 · Published 2026-01-23

LavaLite CMS, a content management system used for building websites and web applications, is vulnerable to a security flaw in its package management feature. An authenticated user can upload malicious scripts disguised as package names or descriptions.

Technical details

A stored cross-site scripting (XSS) vulnerability exists in LavaLite CMS versions up to and including 10.1.0. The flaw is located within the package creation and search components, where the 'Name' and 'Description' fields fail to properly sanitize user-supplied HTML or JavaScript. An authenticated attacker can inject malicious payloads into these fields; when a victim performs a search that returns the compromised package, the payload is rendered without proper output encoding. This allows for the execution of arbitrary script in the context of the victim's browser session, which can lead to session hijacking or credential theft. As of the advisory date, users are advised to monitor for patches or manually implement output encoding for search result displays.
