{"id":"CVE-2026-32769","aliases":["GHSA-hxm7-9q36-c77f","GO-2026-4715"],"url":"https://o3.security/vulnerability/CVE-2026-32769","summary":"Fullchain's Invalid NetworkPolicy enables a malicious actor to pivot into another namespace","details":"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.","published":"2026-03-20T00:18:55.991Z","modified":"2026-07-31T18:30:37.638801687Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/ctfer-io/fullchain","fixedVersion":"0.1.1"}],"fix":{"url":"https://github.com/ctfer-io/fullchain/commit/dbcb90178bcb07a3f5a1efa4c6350f3a6ce34f51","label":"ctfer-io/fullchain@dbcb901"},"references":[{"type":"WEB","url":"https://github.com/ctfer-io/fullchain/releases/tag/v0.1.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32769.json"},{"type":"ADVISORY","url":"https://github.com/ctfer-io/fullchain/security/advisories/GHSA-hxm7-9q36-c77f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32769"},{"type":"FIX","url":"https://github.com/ctfer-io/fullchain/commit/dbcb90178bcb07a3f5a1efa4c6350f3a6ce34f51"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-31T18:30:37.638801687Z"}}
