EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.3 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 75% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

A flaw was found in Red Hat Enterprise Application Platform 8. When an OIDC app that serves multiple tenants attempts to access the second tenant, it should prompt the user to log in again since the second tenant is secured with a different OIDC configuration. The underlying issue is in OidcSessionTokenStore when determining if a cached token should be used or not. This logic needs to be updated to take into account the new "provider-url" option in addition to the "realm" option. EAP-7 does not provide the vulnerable provider-url configuration option in its OIDC implementation and is not affected by this flaw.
