GHSA-h66p-m766-33fv has a CVSS score of 7.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-h66p-m766-33fv?

GHSA-h66p-m766-33fv affects the following packages: com.amazonaws:codedeploy (Maven). Ecosystems affected: Maven.

How do I fix GHSA-h66p-m766-33fv?

Update com.amazonaws:codedeploy to 1.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h66p-m766-33fv is resolved across your whole dependency graph.

How do I detect GHSA-h66p-m766-33fv in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.amazonaws:codedeploy. 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.

How do I mitigate GHSA-h66p-m766-33fv if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-h66p-m766-33fv?

O3 pinpoints whether GHSA-h66p-m766-33fv is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-h66p-m766-33fv actively exploited in the wild?

No public exploit code has been indexed for GHSA-h66p-m766-33fv yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-h66p-m766-33fv?

GHSA-h66p-m766-33fv has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 26th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-h66p-m766-33fv?

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Jenkins project Jenkins AWS CodeDeploy Plugin version 1.19 and earlier contains a Insufficiently Protected Credentials vulnerability in AWSCodeDeployPublisher.java that can result in Credentials Disclosure. This attack appears to be exploitable via local file access.

AWS CodeDeploy Plugin 1.20 and newer stores the AWS Secret Key encrypted in the configuration files on disk and no longer transfers it to users viewing the configuration form in plain text. Existing jobs need to have their configuration saved for existing plain text secret keys to be overwritten.
