CVE-2023-30513Network attack vector

Credential disclosure via missing build-log masking

Published Apr 12, 2023 · Updated Feb 7, 2025

Credential disclosure in Jenkins Kubernetes Plugin 3909.v1f2c633e8590 and earlier allows remote authenticated users to read build secrets. During agent-executed Pipeline sh or bat steps, the plugin forwards credential-bearing output without applying build-log masking. Exposure requires durable-task push logging, enabled by a hidden Java property or automatically by some logging integrations.
