Technical details
A vulnerability in the Core component of Oracle REST Data Services (versions 24.2.0 through 26.1.0) allows a low-privileged attacker with network access via HTTPS to compromise the system. The vulnerability is characterized by a high attack complexity (AC:H) and requires human interaction (UI:R) from a victim other than the attacker. Due to a scope change (S:C), the exploit may impact products beyond the REST Data Services themselves. Successful exploitation can result in unauthorized creation, deletion, or modification of all accessible data, as well as a partial denial of service. The CVSS vector indicates high impacts to confidentiality and integrity, with a low impact on availability.
