What is CVE-2026-25558?

QloApps versions prior to 1.7.0 contain a stored cross-site scripting vulnerability in the admin file manager. This flaw allows authenticated administrators to upload maliciously crafted SVG files, which can contain JavaScript event handlers such as onload. When these files are viewed by any user, arbitrary scripts can be executed in their browser, potentially leading to unauthorized actions or data exposure. This vulnerability underscores the importance of stringent input validation and security measures in web applications.

Affected Version(s)
