In some cases, the UAA allows an authenticated user for a particular client to revoke client tokens for other users on the same client. This occurs only if the client is using opaque tokens or JWT tokens validated using the check_token endpoint. A malicious actor could cause denial of service.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.3},"cwes":[],"references":["http://www.securityfocus.com/bid/101967","https://www.cloudfoundry.org/cve-2017-8031/","http://www.securityfocus.com/bid/101967","https://www.cloudfoundry.org/cve-2017-8031/"],"products":["cloudfoundry:cf-release","cloudfoundry:uaa-release"],"source":"nvd","synced_at":"2026-10-19T20:47:01.408438353+00:00"},"epss":{"cve":"CVE-2017-8031","score":0.01086,"percentile":0.65271,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j4p3-2m2h-cv5f","url":"https://osv.dev/vulnerability/GHSA-j4p3-2m2h-cv5f","summary":"Cloud Foundry UAA Denial of Service through client token revocation endpoint","modified":"2024-12-07T06:07:52.232532Z","packages":[{"ecosystem":"Maven","name":"org.cloudfoundry.identity:cloudfoundry-identity-server","purl":"pkg:maven/org.cloudfoundry.identity/cloudfoundry-identity-server","ranges":[">=4.6.0 <4.7.1"],"fixed":["4.7.1"]},{"ecosystem":"Maven","name":"org.cloudfoundry.identity:cloudfoundry-identity-server","purl":"pkg:maven/org.cloudfoundry.identity/cloudfoundry-identity-server","ranges":[">=4.0.0 <4.5.3"],"fixed":["4.5.3"]},{"ecosystem":"Maven","name":"org.cloudfoundry.identity:cloudfoundry-identity-server","purl":"pkg:maven/org.cloudfoundry.identity/cloudfoundry-identity-server","ranges":["<3.20.1"],"fixed":["3.20.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
