Prior to 0.31.1, a custom frontend could place an invalid SecurityMode value in a crafted build request, and executor/oci/spec_linux.go treated the unsupported value as a non-sandbox mode without requiring the security.insecure entitlement. This disabled Seccomp and AppArmor protections for the build container even though Linux capabilities remained restricted. This issue is fixed in version 0.31.1.","published":"2026-08-19T20:17:19.567","modified":"2026-08-19T20:17:19.567","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/moby/buildkit/commit/3ea6dd0ce7d269cdb8aa23348718e2c1bf64f109","label":"moby/buildkit@3ea6dd0"},"references":[{"type":"WEB","url":"https://github.com/moby/buildkit/commit/3ea6dd0ce7d269cdb8aa23348718e2c1bf64f109"},{"type":"WEB","url":"https://github.com/moby/buildkit/commit/64bbec89ca43dd95b2853edeca240c33c6729910"},{"type":"WEB","url":"https://github.com/moby/buildkit/releases/tag/v0.31.1"},{"type":"WEB","url":"https://github.com/moby/buildkit/security/advisories/GHSA-7236-3392-c5c6"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T20:17:19.567"}}
