{"cve":"CVE-2026-61711","nvd":{"published":"2026-08-19T20:17:19.567","modified":"2026-09-09T21:15:59.613","status":"Deferred","description":"BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. 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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":null,"cwes":["CWE-20"],"references":["https://github.com/moby/buildkit/commit/3ea6dd0ce7d269cdb8aa23348718e2c1bf64f109","https://github.com/moby/buildkit/commit/64bbec89ca43dd95b2853edeca240c33c6729910","https://github.com/moby/buildkit/releases/tag/v0.31.1","https://github.com/moby/buildkit/security/advisories/GHSA-7236-3392-c5c6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-61711","score":0.00357,"percentile":0.29455,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7236-3392-c5c6","url":"https://osv.dev/vulnerability/GHSA-7236-3392-c5c6","summary":"BuildKit: Custom frontend could bypass Seccomp/AppArmor","modified":"2026-09-10T03:51:13.277422932Z","packages":[{"ecosystem":"Go","name":"github.com/moby/buildkit","purl":"pkg:golang/github.com/moby/buildkit","ranges":["<0.31.1"],"fixed":["0.31.1"]}]},{"id":"GO-2026-6255","url":"https://osv.dev/vulnerability/GO-2026-6255","summary":"BuildKit: Custom frontend could bypass Seccomp/AppArmor in github.com/moby/buildkit","modified":"2026-09-01T21:56:11.324773536Z","packages":[{"ecosystem":"Go","name":"github.com/moby/buildkit","purl":"pkg:golang/github.com/moby/buildkit","ranges":["<0.31.1"],"fixed":["0.31.1"]}]}],"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).
