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" } } ] } }
