{"cve":"CVE-2026-32769","nvd":{"published":"2026-03-20T01:15:55.780","modified":"2026-06-17T10:36:21.197","status":"Analyzed","description":"Fullchain is an umbrella project for deploying a ready-to-use CTF platform. In versions prior to  0.1.1, due to a mis-written NetworkPolicy, a malicious actor can pivot from a subverted application to any Pod out of the origin namespace. The flawed inter-ns NetworkPolicy breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement. This issue has been fixed in version 0.1.1. To workaround, delete the failing network policy that should be prefixed by inter-ns- in the target namespace.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-284"],"references":["https://github.com/ctfer-io/fullchain/commit/dbcb90178bcb07a3f5a1efa4c6350f3a6ce34f51","https://github.com/ctfer-io/fullchain/releases/tag/v0.1.1","https://github.com/ctfer-io/fullchain/security/advisories/GHSA-hxm7-9q36-c77f"],"products":["ctfer:fullchain"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32769","score":0.0051,"percentile":0.43539,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hxm7-9q36-c77f","url":"https://osv.dev/vulnerability/GHSA-hxm7-9q36-c77f","summary":"Fullchain's Invalid NetworkPolicy enables a malicious actor to pivot into another namespace","modified":"2026-05-05T15:58:22.553303Z","packages":[{"ecosystem":"Go","name":"github.com/ctfer-io/fullchain","purl":"pkg:golang/github.com/ctfer-io/fullchain","ranges":["<0.1.1"],"fixed":["0.1.1"]}]},{"id":"GO-2026-4715","url":"https://osv.dev/vulnerability/GO-2026-4715","summary":"Fullchain's Invalid NetworkPolicy enables a malicious actor to pivot into another namespace in github.com/ctfer-io/fullchain","modified":"2026-03-26T21:03:00.701286Z","packages":[{"ecosystem":"Go","name":"github.com/ctfer-io/fullchain","purl":"pkg:golang/github.com/ctfer-io/fullchain","ranges":["<0.1.1"],"fixed":["0.1.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
