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.","evidence":"cve:CVE-2026-88883","products":[{"name":{"value":"renovate","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"renovate-ce","evidence":"/containers/cna/affected/1/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"renovate-ee-server","evidence":"/containers/cna/affected/2/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"renovate-ee-worker","evidence":"/containers/cna/affected/3/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"mend-renovate-ce","evidence":"/containers/cna/affected/4/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"mend-renovate-enterprise-edition","evidence":"/containers/cna/affected/5/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-88883","aliases":["CVE-2026-88883"],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","baseScore":8.3,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","userInteraction":"NONE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","subIntegrityImpact":"NONE","vulnIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"HIGH","vulnConfidentialityImpact":"HIGH"}},{"format":"CVSS","cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":7.7,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"renovatebot","product":"renovate","versions":[{"status":"affected","version":"0","lessThan":"44.14.4","versionType":"semver"},{"status":"unaffected","version":"44.14.4","versionType":"semver"}],"defaultStatus":"unaffected"},{"vendor":"mend","product":"renovate-ce","versions":[{"status":"affected","version":"0","lessThan":"15.4.0","versionType":"semver"},{"status":"unaffected","version":"15.4.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"vendor":"mend","product":"renovate-ee-server","versions":[{"status":"affected","version":"0","lessThan":"15.4.0","versionType":"semver"},{"status":"unaffected","version":"15.4.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"vendor":"mend","product":"renovate-ee-worker","versions":[{"status":"affected","version":"0","lessThan":"15.4.0","versionType":"semver"},{"status":"unaffected","version":"15.4.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"vendor":"mend","product":"mend-renovate-ce","versions":[{"status":"affected","version":"0","lessThan":"15.4.0","versionType":"semver"},{"status":"unaffected","version":"15.4.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"vendor":"mend","product":"mend-renovate-enterprise-edition","versions":[{"status":"affected","version":"0","lessThan":"10.4.0","versionType":"semver"},{"status":"unaffected","version":"10.4.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"modified":"2026-09-29T22:10:39.458Z","provider":"cve","references":["https://github.com/renovatebot/renovate/security/advisories/GHSA-4hmw-qw74-vrhm","https://www.vulncheck.com/advisories/renovate-before-44.14.4-tls-private-key-log-sanitisation"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-88883","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-10T14:18:26.314591Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-10T14:55:53.845Z"}}],"cna":{"orgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","shortName":"VulnCheck","dateUpdated":"2026-09-29T22:10:39.458Z"}}},"related_cves":[{"value":"CVE-2026-88883","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":4064,"next_before":4064}
