The supported version that is affected is 26.1. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Trusted Answer Search executes to compromise Oracle Trusted Answer Search.  Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Trusted Answer Search, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in  unauthorized update, insert or delete access to some of Oracle Trusted Answer Search accessible data as well as  unauthorized read access to a subset of Oracle Trusted Answer Search accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Trusted Answer Search. CVSS 3.1 Base Score 5.0 (Confidentiality, Integrity and Availability impacts).
