Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Dapr is a portable, event-driven, runtime for building distributed applications across cloud and edge. Dapr sends the app token of the invoker app instead of the app token of the invoked app. This causes of a leak of the application token of the invoker app to the invoked app when using Dapr as a gRPC proxy for remote service invocation. This vulnerability impacts Dapr users who use Dapr as a gRPC proxy for remote service invocation as well as the Dapr App API token functionality. An attacker could exploit this vulnerability to gain access to the app token of the invoker app, potentially compromising security and authentication mechanisms. This vulnerability was patched in version 1.13.3.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-200

The application discloses data — error detail, internal paths, tokens, or other users' records — to someone who shouldn't see it. On its own it can look minor, but it hands attackers the map they need for a larger attack. Remediation is about minimising what's returned and enforcing authorization on every piece of data.

Recommended fix High confidence

1.13.3 or later

  1. 1. Identify the current Dapr runtime version currently deployed in your environment
  2. 2. If running a version prior to 1.13.3 and using Dapr as a gRPC proxy for remote service invocation with App API token functionality, plan an upgrade to version 1.13.3 or later
  3. 3. Backup your Dapr configuration and state before performing the upgrade
  4. 4. Upgrade the Dapr runtime to version 1.13.3 or later using your deployment method (e.g., Helm chart upgrade, Dapr CLI upgrade, or Kubernetes operator update)
  5. 5. Verify the upgrade was successful by checking the Dapr runtime version
  6. 6. Test that gRPC proxy remote service invocation works correctly with the App API token functionality
