For deployments that do use realm-based authorization, using a renewal profile that additionally restricts renewal requests to the original requester narrows exposure: the shipped caDirUserRenewal.cfg profile configures authz.acl=user_origreq=\"auth_token.uid\", which independently blocks cross-user renewal by comparing the renewing caller's UID against the UID that submitted the original request. This is a partial mitigation only -- it is realm-blind rather than realm-aware, so a UID collision across two independently-administered realms' user directories would still bypass it -- and it does not apply to caManualRenewal.cfg or other shipped renewal profiles that configure no authz.acl, which remain exploitable as described. No complete mitigation is available; apply the update once released."}],"timeline":[{"lang":"en","time":"2026-07-21T09:34:01.000Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-07-24T00:00:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank Arpit Jain (Github: arpitjain099) for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-11-06T18:05:36.949Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-25T00:53:34.296639Z","id":"CVE-2026-17039","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-25T00:53:43.085Z"}}]}}
