Renovate before 44.14.4 TLS Private Key Log Sanitisation

Type: advisorySource: Official CVE List1 source record

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.
