CVE-2022-31055 Information

Description

kCTF is a Kubernetes-based infrastructure for capture the flag (CTF) competitions. Prior to version 1.6.0 the kctf cluster set-src-ip-ranges was broken and allowed traffic from any IP. The problem has been patched in v1.6.0. As a workaround those who want to test challenges privately can mark them as public: false and use kctf chal debug port-forward to connect.
