AWS SDK for Rust will log AWS credentials when TRACE-level logging is enabled for request sending

CVE-2023-30610GHSA-mjv9-vp6w-3rc9

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (aws-sigv4 0.55.1, 0.54.2, 0.53.2, 0.52.1, 0.51.1, 0.49.1, 0.48.1, 0.47.1, 0.46.1, 0.15.1, 0.14.1, 0.13.1, 0.12.1, 0.11.1, 0.10.2, 0.9.1, 0.8.1, 0.7.1, 0.6.1, 0.5.3, 0.4.2, 0.3.1, 0.2.1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

The awssigv4::SigningParams struct had a derived Debug implementation. When debug-formatted, it would include a user's AWS access key, AWS secret key, and security token in plaintext. When TRACE-level logging is enabled for an SDK, SigningParams is printed, thereby revealing those credentials to anyone with access to logs. Impact All users of the AWS SDK for Rust who enabled TRACE-level logging, either globally (e.g. RUSTLOG=trace), or for the aws-sigv4 crate specifically. Patches - Versions = 0.55.1 - 0.54.2 - 0.53.2 - 0.52.1 - 0.51.1 - 0.50.1 - 0.49.1 - 0.48.1 - 0.47.1 - 0.46.1 - 0.15.1 - 0.14.1 - 0.13.1 - 0.12.1 - 0.11.1 - 0.10.2 - 0.9.1 - 0.8.1 - 0.7.1 - 0.6.1 - 0.5.3 - 0.3.1 - 0.2.1 Workarounds Disable TRACE-level logging for AWS Rust SDK crates.

# Patch Next advisory brief: CVE-2023-30610

Advisory: AWS SDK for Rust will log AWS credentials when TRACE-level logging is enabled for request sending
IDs: CVE-2023-30610, GHSA-mjv9-vp6w-3rc9
Record: https://patchnext.com/advisories/cve-2023-30610 (revision 1, source checked 26 Oct 2026, 15:42 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: aws-sigv4 0.55.1, 0.54.2, 0.53.2, 0.52.1, 0.51.1, 0.49.1, 0.48.1, 0.47.1, 0.46.1, 0.15.1, 0.14.1, 0.13.1, 0.12.1, 0.11.1, 0.10.2, 0.9.1, 0.8.1, 0.7.1, 0.6.1, 0.5.3, 0.4.2, 0.3.1, 0.2.1. A vendor fix does not mean a deployment is fixed.

## Affected components

## Suggested inspection (read-only)
- crates.io aws-sigv4: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on aws-sigv4.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
