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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-18 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-88883.json)","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":42.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
