Vulnerability from github – Published: 2026-09-23 12:31 – Updated: 2026-09-23 12:31

Details

Reflected Cross-Site Scripting (XSS) in Microweber. The vulnerability lies in the ‘group’ parameter of the ‘/admin/settings’ endpoint in the administration panel. A successful exploit allows an attacker to trick an authenticated user into executing malicious JavaScript code in their browser. This enables the attacker to perform actions without the victim’s consent, steal confidential information or hijack the user’s session.

Severity

5.9 (Medium)
