Technical details
A Server-Side Request Forgery (SSRF) vulnerability exists in MaxKB's workflow template import functionality within `apps/application/serializers/application.py`. The application accepts a user-provided `downloadUrl` and fetches it using the Python `requests` library without performing URL validation or filtering for private IP ranges (RFC1918, link-local, or cloud metadata endpoints). An authenticated attacker can exploit this to perform internal network reconnaissance or access sensitive local services. The vulnerability is resolved in version 2.9.1 by implementing proper URL validation and IP blacklisting.
