A remote unauthenticated attacker can poison the discovery document so relying parties performing dynamic (unpinned) discovery fetch the JWKS from an attacker-controlled server, causing attacker-signed JWTs to be accepted. Exploitation requires the OIDC server enabled without a configured jwt-issuer or oidc-allowed-hosts."}], "tags": ["x_open-source"], "datePublic": "2026-05-27T00:00:00.000Z", "problemTypes": [{"descriptions": [{"lang": "en", "cweId": "CWE-346", "description": "Origin Validation Error", "type": "CWE"}]}], "affected": [{"vendor": "dapr", "product": "dapr", "defaultStatus": "unaffected", "versions": [{"status": "affected", "version": "1.17.0", "versionType": "semver"}, {"status": "affected", "version": "1.18.0", "versionType": "semver"}], "repo": "https://github.com/dapr/dapr"}], "metrics": [{"format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}], "cvssV3_1": {"attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "NONE", "integrityImpact": "HIGH", "availabilityImpact": "NONE", "version": "3.1", "baseSeverity": "HIGH", "baseScore": 7.5, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}}, {"format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}], "cvssV4_0": {"attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "PRESENT", "privilegesRequired": "NONE", "userInteraction": "NONE", "vulnConfidentialityImpact": "NONE", "subConfidentialityImpact": "NONE", "vulnIntegrityImpact": "HIGH", "subIntegrityImpact": "NONE", "vulnAvailabilityImpact": "NONE", "subAvailabilityImpact": "NONE", "exploitMaturity": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED", "version": "4.0", "baseSeverity": "HIGH", "baseScore": 8.2, "vectorString": "CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}}], "references": [{"url": "https://github.com/dapr/dapr/pull/10027", "name": "Fix PR", "tags": ["issue-tracking"]}, {"url": "https://github.com/dapr/dapr/pull/10028", "name": "Backport release-1.17", "tags": ["issue-tracking"]}, {"url": "https://github.com/dapr/dapr/pull/10029", "name": "Backport release-1.18", "tags": ["issue-tracking"]}, {"url": "https://www.vulncheck.com/advisories/dapr-oidc-discovery-issuer-and-jwks-uri-injection-via-unvalidated-x-forwarded-host", "tags": ["third-party-advisory"]}], "credits": [{"lang": "en", "value": "George Chen", "type": "finder"}], "x_generator": {"engine": "vulncheck-endgame"}}}}
