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
Garden provides automation for Kubernetes development and testing. Prior tov ersions 0.13.17 and 0.12.65, Garden has a dependency on the cryo library, which is vulnerable to code injection due to an insecure implementation of deserialization. Garden stores serialized objects using cryo in the Kubernetes `ConfigMap` resources prefixed with `test-result` and `run-result` to cache Garden test and run results. These `ConfigMaps` are stored either in the `garden-system` namespace or the configured user namespace. When a user invokes the command `garden test` or `garden run` objects stored in the `ConfigMap` are retrieved and deserialized. This can be used by an attacker with access to the Kubernetes cluster to store malicious objects in the `ConfigMap`, which can trigger a remote code execution on the users machine when cryo deserializes the object. In order to exploit this vulnerability, an attacker must have access to the Kubernetes cluster used to deploy garden remote environments. Further, a user must actively invoke either a `garden test` or `garden run` which has previously cached results. The issue has been patched in Garden versions `0.13.17` (Bonsai) and `0.12.65` (Acorn). Only Garden versions prior to these are vulnerable. No known workarounds are available.

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.

dbcve analysis
How this class of weakness works · CWE-94

The application evaluates attacker-influenced input as code, handing them a way to run logic inside the process. Depending on the runtime this can escalate directly to remote code execution. Remediation means removing dynamic evaluation of untrusted input and replacing it with safe, data-driven alternatives.

Fixed in 0.12.650.13.17
Vendor patch github.com →
Recommended fix High confidence

0.12.65 (Acorn) or 0.13.17 (Bonsai) depending on current release line

  1. Upgrade Garden CLI to version 0.12.65 if using the 0.12.x (Acorn) release line
  2. Upgrade Garden CLI to version 0.13.17 if using the 0.13.x (Bonsai) release line
  3. After upgrading, verify that cached ConfigMaps in the Kubernetes cluster (in garden-system namespace or configured user namespace) with prefixes 'test-result' and 'run-result' are cleared or will be regenerated on next test/run commands
  4. Run 'garden test' or 'garden run' commands to ensure normal operation with the patched version
Caveat Ensure compatibility with your Kubernetes cluster and existing Garden configuration files; major version differences may have feature changes
