Description
### 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.
