AI Analysis

Impact

Vulnerability in the RAPID component of Oracle MySQL Server and MySQL Cluster allows a high‑privileged attacker with network access through one of the supported protocols to force the database to hang or crash, resulting in a complete denial of service. The weakness is identified by CVSS 3.1 base score 4.4 and impacts only availability, with no effect on confidentiality or integrity. The flaw arises from improper access control (CWE‑284) and input validation weaknesses (CWE‑617) that permit malicious requests to trigger a resource exhaustion condition.

Affected Systems

Oracle MySQL Server versions 9.7.0 through 9.7.3 and 26.7.0 through 26.7.1, as well as the corresponding MySQL Cluster releases within those same version ranges, are affected.

Risk and Exploitability

Attacks require a high‑privilege attacker with network access via a supported protocol. The exploit path involves sending specially crafted requests that cause resource exhaustion, leading to a crash or lock‑up. The EPSS score of <1% indicates a very low likelihood that this flaw will be exploited in the wild, and the vulnerability is not listed in the CISA KEV catalog. Consequently, while the availability impact could disrupt critical database operations, the overall risk remains limited due to the low exploit probability and the need for privileged network access.
