CVE-2023-0690
MEDIUMCVE-2023-0690 is a medium-severity (CVSS 5) CWE-312 vulnerability in github.com/hashicorp/boundary. O3 Security confirms whether CVE-2023-0690 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Boundary Workers Store Rotated Credentials in Plaintext Even When a Key Management Service Configured

github.com/hashicorp/boundaryReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
HashiCorp Boundary from 0.10.0 through 0.11.2 contain an issue where when using a PKI-based worker with a Key Management Service (KMS) defined in the configuration file, new credentials created after an automatic rotation may not have been encrypted via the intended KMS. This would result in the credentials being stored in plaintext on the Boundary PKI worker’s disk.
This issue is fixed in version 0.12.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/hashicorp/boundary. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/hashicorp/boundary to 0.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-0690 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2023-0690 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-0690. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
