AnalysisAI
Unauthenticated, remote attackers with HTTP reachability to Hyperion Financial Management 11.2.26.0.000 can bypass authentication in the product's Security component and then create, delete or modify critical financial data and read all HFM-accessible data, matching Oracle's own 'easily exploitable' rating and a CVSS 3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, no availability impact). The CWE-287 classification frames this as a pre-authentication control failure rather than a memory-safety bug, so a crafted request that reaches the vulnerable endpoint is treated as legitimate; CISA's SSVC framework records Exploitation: none, Automatable: yes and Technical Impact: total. …
