GHSA-vxg3-w9rv-rhr2 is a high-severity (CVSS 7.3) vulnerability in github.com/edgelesssys/contrast. A fix is available for github.com/edgelesssys/contrast — see the affected versions and patch details below.
Contrast leaks workload secrets to logs on INFO level
Real-World Exposure
github.com/edgelesssys/contrastReal-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
This is the same vulnerability as https://github.com/edgelesssys/contrast/security/advisories/GHSA-h5f8-crrq-4pw8. The original vulnerability had been fixed for release v1.8.1, but the fix was not ported to the main branch and thus not present in releases v1.9.0 ff.
Below is a brief repetition of the relevant sections from the first GHSA, where you can find the full details.
Impact
- Workload secrets are visible to Kubernetes users with
getorlistpermission onpods/logs, and thus need to be considered compromised. - Since workload secrets are used for encrypted storage and Vault integration, those need to be considered compromised, too.
Patches
Patches:
- https://github.com/edgelesssys/contrast/commit/5a5512c4af63c17bb66331e7bd2768a863b2f225
- https://github.com/edgelesssys/contrast/commit/cf58026b30c43fe7df91eac5322da02e1725d554
The patches are released with v1.12.2 and v1.13.0 (not yet published). Since the secrets are compromised, Contrast needs to be initialized from scratch.
Workarounds
Existing workload secrets are compromised. The Contrast cluster needs to be newly initialized, and logging needs to be turned off.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/edgelesssys/contrast, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/edgelesssys/contrast to 1.12.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vxg3-w9rv-rhr2 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-vxg3-w9rv-rhr2 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-vxg3-w9rv-rhr2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-vxg3-w9rv-rhr2 in your dependencies?
O3 Security finds GHSA-vxg3-w9rv-rhr2 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
