+## Reporting Security Issues
+
+If you believe you have found a security vulnerability in browser-use, please report it through coordinated disclosure.
+
+**Please do not report security vulnerabilities through the repository issues, discussions, or pull requests.**
+
+Instead, please open a new [Github security advisory](https://github.com/browser-use/web-ui/security/advisories/new).
+
+Please include as much of the information listed below as you can to help me better understand and resolve the issue:
+
+* The type of issue (e.g., buffer overflow, SQL injection, or cross-site scripting)
+* Full paths of source file(s) related to the manifestation of the issue
+* The location of the affected source code (tag/branch/commit or direct URL)
+* Any special configuration required to reproduce the issue
+* Step-by-step instructions to reproduce the issue
+* Proof-of-concept or exploit code (if possible)
+* Impact of the issue, including how an attacker might exploit the issue
+
+This information will help me triage your report more quickly.
