CyberRota Analysis
AI-GeneratedRenovate versions prior to 44.14.4, along with specific Mend Renovate CE/EE images and Helm charts, expose TLS private keys in cleartext within logs due to incomplete sanitization. This vulnerability allows unauthorized users with log access to recover sensitive private key information, potentially compromising secure communications. Organizations utilizing Mutual TLS with Renovate should prioritize upgrading to the fixed version or implementing the workaround to safeguard their private keys.

Original NVD Description
Renovate is an automated dependency update tool. In versions before 44.14.4 (and Mend Renovate CE/EE images before 15.4.0 and the mend-renovate-enterprise-edition Helm chart before 10.4.0), log sanitisation for TLS private keys used for Mutual TLS was incomplete. While the value of hostRules[].httpsPrivateKey was redacted in the field itself, the same private key value was not redacted if it also appeared elsewhere — for example in another configuration option or in a log message under a key other than httpsPrivateKey — causing the full private key to be written to Renovate's logs in cleartext. This affects deployments that configure Mutual TLS through hostRules[].httpsPrivateKey without passing the value through the documented `secrets` configuration. Anyone able to read the resulting logs can recover the private key. The issue is fixed in Renovate 44.14.4, which redacts any value supplied as hostRules[].httpsPrivateKey wherever it appears in the logs; as a workaround, supply the key via the `secrets` configuration.
