What an attacker can do
An authenticated user can bypass the SSRF / private-IP protections in SendWebRequestBlock and reach internal network services. _is_ip_blocked() in backend/backend/util/request.py does not normalize IPv4-mapped IPv6 addresses before checking resolved IPs against the blocked IPv4 ranges, and does not block special-use ranges such as 100.64.0.0/10 (CGNAT, RFC 6598). Vendor/CNA’s CVSS 3.1 assessment (base score 8.5/10) rates confidentiality, integrity and availability impact as high.
