{"id":"CVE-2026-32769","state":"PUBLISHED","title":"Fullchain's Invalid NetworkPolicy enables a malicious actor to pivot into another namespace","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.","publishedAt":"2026-03-20T00:18:55.991Z","updatedAt":"2026-03-20T20:01:28.750Z","severity":{"score":7.1,"label":"High","version":"4.0","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","source":"GitHub_M"},"assigner":"GitHub_M","products":["ctfer-io fullchain"],"affected":[{"vendor":"ctfer-io","product":"fullchain","versions":[{"version":"< 0.1.1","status":"affected"}]}],"references":["https://github.com/ctfer-io/fullchain/security/advisories/GHSA-hxm7-9q36-c77f","https://github.com/ctfer-io/fullchain/commit/dbcb90178bcb07a3f5a1efa4c6350f3a6ce34f51","https://github.com/ctfer-io/fullchain/releases/tag/v0.1.1"],"weaknesses":["CWE-284"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/32xxx/CVE-2026-32769.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-32769","state":"PUBLISHED","datePublished":"2026-03-20T00:18:55.991Z","dateUpdated":"2026-03-20T20:01:28.750Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-13T18:53:03.534Z"},"containers":{"cna":{"title":"Fullchain's Invalid NetworkPolicy enables a malicious actor to pivot into another namespace","descriptions":[{"lang":"en","value":"Fullchain is an umbrella project for deploying a ready-to-use CTF platform.
