Renovate 是一个自动化的依赖更新工具。在 44.14.4 之前的版本中（以及 Mend Renovate CE/EE 镜像 15.4.0 之前、mend-renovate-enterprise-edition Helm Chart 10.4.0 之前），针对用于双向 TLS（Mutual TLS）的 TLS 私钥的日志脱敏处理并不完整。虽然 字段本身的值会被掩盖（redacted），但如果该私钥值出现在其他位置——例如在其他配置项中，或出现在日志中并非 键下的消息里——那么该私钥值就不会被掩盖，导致完整的私

Vulnerability Title
Renovate before 44.14.4 TLS Private Key Log Sanitisation
来源: CVE Program / CVE List V5
Vulnerability 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.
