**Name of the Vulnerable Software and Affected Versions** LGSL versions prior to 7.0.0 **Description** A stored cross-site scripting (XSS) vulnerability was identified in LGSL. The issue arises from improper sanitation of user input. The function `lgsl query 40` in `lgsl protocol.php` has implemented an HTTP crawler, which makes a request to the registered game server and renders javascript on the info page when crawling the malicious `/info` endpoint with a payload. This information is being displayed via `lgsl details.php`. Everyone who accesses this page will be affected by this attack. **Recommendations** For versions prior to 7.0.0, update to version 7.0.0 or later to resolve the issue. As a temporary workaround, consider disabling the `lgsl query 40` function in `lgsl protocol.php` until a patch is available. Restrict access to the `/info` endpoint to minimize the risk of exploitation. Avoid using the `EconomyDesc` field in the JSON payload served at `/info` until the issue is resolved.
