A flaw was found in Picketlink Federation SAML; the unsolcited response handler would accept forged assertions with no verification or validation, permitting an unauthed attacker to authenticate as any principal in any role.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
