In versions before 44.11.2 (and Mend Renovate CE/EE images and charts before 15.4.0, and mend-renovate-enterprise-edition helm chart before 10.4.0), when listing new package versions from a NuGet registry Renovate follows pagination URLs supplied by the registry in the HTTP `Link` header without verifying that the target has the same origin as the configured registry. Registry credentials are attached to the request for the 'next' page, so a malicious or compromised NuGet registry can return a `Link` header pointing at an attacker-controlled server and cause Renovate to send the registry credentials to that server. Exploitation requires the remote registry to be malicious or compromised; such a registry would normally already have received the credentials on the initial request, so the issue primarily allows the credentials to be delivered to an additional, attacker-chosen host. The fix restricts pagination to the same origin; the previous behaviour can be re-enabled with the RENOVATE_X_NUGET_PAGINATION_ALLOW_CROSS_ORIGIN option.","evidence":"cve:CVE-2026-88882","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":"critical","structured":{"id":"CVE-2026-88882","aliases":["CVE-2026-88882"],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","baseScore":9.2,"attackVector":"NETWORK","baseSeverity":"CRITICAL","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","userInteraction":"NONE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","subIntegrityImpact":"NONE","vulnIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"HIGH","vulnConfidentialityImpact":"HIGH"}},{"format":"CVSS","cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":8.6,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"renovatebot","product":"renovate","versions":[{"status":"affected","version":"0","lessThan":"44.11.2","versionType":"semver"},{"status":"unaffected","version":"44.11.2","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":"2026-09-29T22:10:38.475Z","provider":"cve","references":["https://github.com/renovatebot/renovate/security/advisories/GHSA-rh7w-ccch-gh49","https://www.vulncheck.com/advisories/renovate-before-44.11.2-credential-exfiltration-via-link-header"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-88882","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-10T14:09:03.832818Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-10T14:09:13.720Z"}}],"cna":{"orgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","shortName":"VulnCheck","dateUpdated":"2026-09-29T22:10:38.475Z"}}},"related_cves":[{"value":"CVE-2026-88882","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":4060,"next_before":4060}
