Summary

BuildKit: Custom frontend could bypass Seccomp/AppArmor

Severity: medium
EPSS: 0.4% (p29)
CWE: CWE-20
Also known as: GHSA-7236-3392-c5c6
Published: 2026-08-19
Updated: 2026-08-19

Advisory details

Impact

A custom frontend could send a crafted build request that disabled Seccomp and AppArmor protections for the build container, even if the user did not explicitly allow the security.insecure entitlement. Other security measures, like Linux capabilities were still applied to these containers.

Patches

Problem has been fixed in versions v0.31.1+

Workarounds

Only use BuildKit frontends from trusted providers.
