CVE-2026-50235

Lyrion Music Server 9.2.0 Reflected XSS via search Parameters

Published Jun 5, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed

Description

Lyrion Music Server 9.2.0 contains a reflected cross-site scripting vulnerability in advanced search parameters that fail to properly sanitize user input before displaying it in search forms. Attackers can inject malicious scripts through unfiltered search parameters to execute arbitrary JavaScript in users' browsers and steal session information.

Analysis

Technical impact

The vulnerability is a reflected cross‑site scripting flaw in the advanced search feature of Lyrion Music Server 9.2.0. Search parameters are displayed back to the user without proper escaping, enabling an attacker to inject and execute arbitrary JavaScript in a victim’s browser. This can lead to theft of session cookies, defacement or redirecting users to malicious sites. The flaw is a classic input validation weakness (CWE‑79).

Affected Systems

The only version explicitly mentioned as vulnerable is Lyrion Music Server 9.2.0, part of the LMS Community edition. No other versions or editions are noted in the advisory.

Risk and Exploitability

The advisory assigns a CVSS score of 5.1, indicating a moderate impact, and there is no EPSS score available, so the exploitation probability is unclear. The vulnerability is not listed in the CISA KEV catalog. Attackers need only supply a specially crafted search URL or form submission that contains malicious script; the flaw is reflected immediately in the response presented to the user. If a user opens the crafted link in a browser, the attacker can acquire the victim's session cookies or other sensitive browser data.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Update Lyrion Music Server to a version where the search parameters are properly sanitized.
Apply server‑side input validation and encode all user‑supplied search strings before displaying them back.
Enforce a Content Security Policy that disallows inline scripts and restricts script sources to trusted domains.
If an update is not possible, disable the advanced search feature or block the affected URLs.
