How to Fix CVE-2025-0495

To remediate this vulnerability, upgrade all affected Github.com/docker/buildx dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/docker/buildx fixed: 0.21.3 
Upgrade github.com/docker/buildx to 0.21.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/docker/buildx

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-0495, inspect your project dependencies for Github.com/docker/buildx:

inspect dependencies for github.com/docker/buildx

Analyze the terminal output to locate any version of Github.com/docker/buildx in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.21.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-532: Insertion of Sensitive Information into Log File, where the product writes sensitive information to a log file. In Github.com/docker/buildx, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
