CVE-2026-6150

Vulnerability

Description

The Simple Laundry System version 1.0 contains a reflected cross-site scripting (XSS) vulnerability in the /checkupdatestatus.php file. The root cause is that the serviceId parameter is echoed directly into the web page without any sanitization or encoding, allowing an attacker to inject arbitrary HTML and JavaScript code [1].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious URL that includes a serviceId parameter containing JavaScript, such as ``. No authentication or authorization is required to trigger the vulnerability; any victim who clicks the crafted link will have the script executed in their browser [1].

Impact

Successful exploitation enables an attacker to steal cookies, session tokens, or other sensitive information from the victim, perform actions on behalf of the victim (such as modifying account settings or initiating transactions), deface the web application, redirect users to malicious sites, or potentially gain control of the victim's browser [1].

Mitigation

Status

As of the publication date, no official patch has been released by code-projects. Administrators should implement proper input validation and output encoding for all user-supplied data, particularly the serviceId parameter, and consider deploying a Web Application Firewall (WAF) as an interim control until a vendor fix is available [1][2].
