Credential disclosure via unredacted command arguments
Published Mar 17, 2025 · Updated Mar 18, 2025
Sensitive information exposure in Docker Buildx 0.21.2 and earlier allows local users to read cache credentials from build traces. TraceCurrentCommand passed the complete process argument vector from os.Args into the OpenTelemetry command attribute, preserving cache-to and cache-from credential values. Exposure requires a user to supply credentials as cache backend attributes and an attacker to access a custom telemetry collector or BuildKit history; environment-based GitHub cache tokens and registry authentication are unaffected.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
