Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Mautic/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Summary\nA Server-Side Request Forgery (SSRF) vulnerability exists in the Mautic Focus component (`MauticFocusBundle`). Under certain conditions, insufficiency in validating user-supplied URLs allows authenticated users to trigger outbound HTTP requests from the hosting server.\n\n### Impact\nAn authenticated user with access to the Mautic panel can exploit this vulnerability to perform internal port probing or force the server to initiate requests to external or arbitrary internal destinations. This can enable internal network reconnaissance or mapping of firewalled infrastructure.\n\n### Patched Versions\nThis security issue has been fixed in the following releases:\n* **7.1.2**\n* **6.0.9**\n* **5.2.11**\n* **4.4.20** [ELTS](https://mautic.org/extended-long-term-support-elts/)\n\nMautic strongly recommend upgrading to the latest version corresponding to your release branch.\n\n### Workarounds\nThere are no official workarounds. To completely mitigate the exposure without upgrading, disabling or limiting external network access from the Mautic web server to internal-only subnets/local hosts is recommended.",
