Server-Side Request Forgery (SSRF)

CVE-2025-9821

Low
2.7/10

Summary

Users with webhook permissions can conduct Server-Side Request Forgery (SSRF) via webhooks. If they have permission to view the webhook logs, the (partial) request response is also disclosed. When sending webhooks, the destination is not validated, causing SSRF. Due to this, the impact is a firewall bypass to interact with internal services. This issue affects mautic/core and mautic/core-lib versions 4.4.0-beta through 4.4.16, 5.0.0-alpha through 5.2.7, 6.0.0-alpha through 6.0.4, and 7.0.0-alpha.

CWE-918 - Server-Side Request Forgery (SSRF)

Server-side request forgery (SSRF) is a weakness that allows an attacker to send an arbitrary request, making it appear that the request was sent by the server. This request may bypass a firewall that would normally prevent direct access to the URL. The impact of this vulnerability can vary from unauthorized access to files and sensitive information to remote code execution.
