Secrets leakage to telemetry endpoint via cache backend configuration via buildx
cve-program · CVE-2025-0495
PublishedBuildx is a Docker CLI plugin that extends build capabilities using BuildKit. Cache backends support credentials by setting secrets directly as attribute values in cache-to/cache-from configuration. When supplied as user input, these secure values may be inadvertently captured in OpenTelemetry traces as part of the arguments and flags for the traced CLI command. OpenTelemetry traces are also saved in BuildKit daemon's history records. This vulnerability does not impact secrets passed to the Github cache backend via environment variables or registry authentication.

Published### Impact Some cache backends allow configuring their credentials by setting secrets directly as attribute values in `cache-to/cache-from` configuration. If this was done by the user, these secure values could be captured together with OpenTelemetry trace as part of the arguments and flags for the traced CLI command. Passing tokens to Github cache backend via environment variables or using registry authentication is not affected. If you passed a token value like this and use a custom OpenTelemetry collector for computing traces you should make sure that your traces are kept secure. OpenTelemetry traces are also saved in BuildKit daemon's history records. ### Patches Issue has been fixed in Buildx v0.21.3 or newer. ### Workarounds Avoid passing cache backend credentials with CLI arguments. Make sure access to traces and BuildKit history records is kept secure.

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
