+## Summary
+
+A critical vulnerability in ProjectSend, a widely-used open-source file-sharing platform, has been actively exploited. The vulnerability, found in versions prior to r1720, enables unauthenticated attackers to modify application configurations via improperly authorised requests. This allows exploitation scenarios such as enabling unauthorised user registration, uploading PHP webshells, or embedding malicious JavaScript, leading to server compromise.
+
+## Recommendations
+
+To remediate {% cve CVE-2024-11680 %}, upgrade ProjectSend to version r1720 or later to resolve the improper authorisation vulnerability. Limit public access by applying strict network controls and review server logs for unusual activity, especially targeting `options.php` or unauthorised uploads in `upload/files/`. For any compromised systems, remove malicious files, restore original configurations, and investigate further for signs of exploitation. Establish a patch management process to ensure timely updates and minimise exposure to future vulnerabilities
+
+## What we are doing
