| Doc Text: |
A flaw was found in Docker Buildx. When building multiple targets simultaneously using an untrusted Bake definition, filesystem paths from certain targets fail to be verified against approved access entitlements. An attacker could exploit this flaw by enticing a user to execute a malicious build definition, resulting in unauthorized information disclosure of local files accessible to the client without required read permissions.
