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

Multiple Jenkins plugins do not properly mask (i.e., replace with asterisks) credentials printed in the build log from Pipeline steps like sh and bat, when both of the following conditions are met:

  • The credentials are printed in build steps executing on an agent (typically inside a node block).

  • Push mode for durable task logging is enabled. This is a hidden option in Pipeline: Nodes and Processes that can be enabled through the Java system property org.jenkinsci.plugins.workflow.steps.durable_task.DurableTaskStep.USE_WATCHING. It is also automatically enabled by some plugins, e.g., OpenTelemetry and Pipeline Logging over CloudWatch.

The following plugins are affected by this vulnerability:

  • Kubernetes 3909.v1f2c633e8590 and earlier (SECURITY-3079 / CVE-2023-30513)

  • Azure Key Vault 187.va_cd5fecd198a_ and earlier (SECURITY-3051 / CVE-2023-30514)

  • Thycotic DevOps Secrets Vault 1.0.0 (SECURITY-3078 / CVE-2023-30515)

The following plugins have been updated to properly mask credentials in the build log when push mode for durable task logging is enabled:

  • Kubernetes 3910.ve59cec5e33ea_ (SECURITY-3079 / CVE-2023-30513)

  • Azure Key Vault 188.vf46b_7fa_846a_1 (SECURITY-3051 / CVE-2023-30514)

As of publication of this advisory, there is no fix available for the following plugin:

  • Thycotic DevOps Secrets Vault 1.0.0 (SECURITY-3078 / CVE-2023-30515)

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.csanchez.jenkins.plugins:kubernetes, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.csanchez.jenkins.plugins:kubernetes to 3910.ve59cec5e33ea or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-30513 is resolved across your whole dependency graph.

  3. 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.
