Summary
There is an privilege escalation vulnerability in organization-specific logins in Esri Portal for ArcGIS versions 10.9 and below that may allow a remote, authenticated attacker who is able to intercept and modify a SAML assertion to impersonate another account (XML Signature Wrapping Attack). In addition patching, Esri also strongly recommends as best practice for SAML assertions to be signed and encrypted.
