{"id":"CVE-2022-31055","summary":"Improper Access Control in kctf","details":"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.","aliases":["GHSA-4g2v-6qc6-6jv5"],"modified":"2026-04-02T08:00:18.013969Z","published":"2022-06-13T15:40:10Z","database_specific":{"cwe_ids":["CWE-284"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31055.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31055.json"},{"type":"ADVISORY","url":"https://github.com/google/kctf/security/advisories/GHSA-4g2v-6qc6-6jv5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31055"},{"type":"FIX","url":"https://github.com/google/kctf/commit/8cf050be974fcc2fd8aa136701f9a66f2b2a5202"},{"type":"FIX","url":"https://github.com/google/kctf/pull/371"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/google/kctf","events":[{"introduced":"0"},{"fixed":"8cf050be974fcc2fd8aa136701f9a66f2b2a5202"}]}],"versions":["v1.0.0","v1.0.1","v1.0.2","v1.0.3","v1.0.4","v1.0.5","v1.0.6","v1.0.7","v1.0.8","v1.1.0","v1.2.0","v1.2.1","v1.3.0","v1.3.1","v1.3.2","v1.3.3","v1.3.4","v1.4.0","v1.5.0","v1.5.1","v1.5.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-31055.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
