Refresh tokens by design have a longer expiration time than access tokens, allowing the possessor of a refresh token to authenticate longer than expected. This affects the administrative endpoints of the UAA. i.e. /Users, /Groups, etc. However, if the user has been deleted or had groups removed, or the client was deleted, the refresh token will no longer be valid.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-863"],"references":["https://www.cloudfoundry.org/blog/cve-2018-11047/","https://www.cloudfoundry.org/blog/cve-2018-11047/"],"products":["pivotal_software:cloud_foundry_uaa"],"source":"nvd","synced_at":"2026-10-19T20:52:03.425131697+00:00"},"epss":{"cve":"CVE-2018-11047","score":0.01066,"percentile":0.64776,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r4v8-9hgx-vm6m","url":"https://osv.dev/vulnerability/GHSA-r4v8-9hgx-vm6m","summary":"Cloud Foundry UAA accepts refresh token as access token on admin endpoints","modified":"2024-03-01T23:56:40.564538Z","packages":[{"ecosystem":"Maven","name":"org.cloudfoundry.identity:cloudfoundry-identity-server","purl":"pkg:maven/org.cloudfoundry.identity/cloudfoundry-identity-server","ranges":["<4.5.7"],"fixed":["4.5.7"]},{"ecosystem":"Maven","name":"org.cloudfoundry.identity:cloudfoundry-identity-server","purl":"pkg:maven/org.cloudfoundry.identity/cloudfoundry-identity-server","ranges":[">=4.6.0 <4.7.6"],"fixed":["4.7.6"]},{"ecosystem":"Maven","name":"org.cloudfoundry.identity:cloudfoundry-identity-server","purl":"pkg:maven/org.cloudfoundry.identity/cloudfoundry-identity-server","ranges":[">=4.8.0 <4.10.2"],"fixed":["4.10.2"]},{"ecosystem":"Maven","name":"org.cloudfoundry.identity:cloudfoundry-identity-server","purl":"pkg:maven/org.cloudfoundry.identity/cloudfoundry-identity-server","ranges":[">=4.11.0 <4.12.4"],"fixed":["4.12.4"]},{"ecosystem":"Maven","name":"org.cloudfoundry.identity:cloudfoundry-identity-server","purl":"pkg:maven/org.cloudfoundry.identity/cloudfoundry-identity-server","ranges":[">=4.13.0 <4.19.2"],"fixed":["4.19.2"]}]}],"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).
