DescriptionCVE.org

Vulnerability in the Oracle Agile PLM MCAD Connector product of Oracle Supply Chain (component: CAX Client). The supported version that is affected is 3.6. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where Oracle Agile PLM MCAD Connector executes to compromise Oracle Agile PLM MCAD Connector. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Agile PLM MCAD Connector accessible data. CVSS 3.1 Base Score 1.8 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:U/C:L/I:N/A:N).

AnalysisAI

Limited confidentiality exposure in Oracle Agile PLM MCAD Connector 3.6 allows a high-privileged local attacker to read a subset of accessible data under constrained conditions. The CVSS 3.1 base score of 1.8 reflects a worst-case scenario requiring local infrastructure access, high privileges, high attack complexity, and mandatory third-party human interaction - a combination rarely satisfied in practice. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires all of the following simultaneously: (1) the attacker must have a high-privileged account with local logon capability on the infrastructure where Oracle Agile PLM MCAD Connector 3.6 executes - remote network access is insufficient; (2) the attack complexity is high, meaning specific technical conditions beyond the attacker's direct control must align; (3) a separate human user - not the attacker - must interact with the system during the attack window (UI:R). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	Risk signals uniformly point to very low real-world priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation	Apply the patch or update provided in Oracle's Critical Security Patch Update (CSPU) for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report.
