Additionally, if an administrator disables or deletes an IdP (Identity Provider) after a SAML flow has started, the handler still processes the response using the provider snapshot loaded at the start of the request. As a result, an attacker controlling a registered upstream IdP can send unsolicited SAML responses, or replay a legitimately captured response in a different session or after the original flow has ended. In both cases, Casdoor accepts the response and issues a session, enabling persistent unauthorized access."}],"source":{"discovery":"UNKNOWN"},"affected":[{"vendor":"Casdoor","product":"Casdoor","versions":[{"status":"affected","version":"0","lessThanOrEqual":"2.362.0","versionType":"custom"}]}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-346 Origin Validation Error"}]}],"references":[{"url":"https://kb.cert.org/vuls/id/780781"}],"x_generator":{"engine":"VINCE 3.0.41","env":"prod","origin":"https://cveawg.mitre.org/api/cve/CVE-2026-9098"},"providerMetadata":{"orgId":"37e5125f-f79b-445b-8fad-9564f167944b","shortName":"certcc","dateUpdated":"2026-05-28T16:31:42.767Z"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":9.1,"attackVector":"NETWORK","baseSeverity":"CRITICAL","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-06-02T15:50:28.631307Z","id":"CVE-2026-9098","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-02T16:43:43.567Z"}}]}}
