CVE-2025-9291

Severity CVSS v4.0:
HIGH
Type:
CWE-295 Improper Certificate Validation
Publication date:
03/08/2026
Last modified:
07/08/2026

Description

A<br /> certification validation weakness exists in communication between affected<br /> Omada devices and cloud controllers. Certificate identity verification does not<br /> adequately validate that a presented certificate corresponds to the expected<br /> cloud controller hostname, which may allow certificate validation protections<br /> to be bypassed under specific conditions.<br /> <br /> <br /> <br /> <br /> <br /> Successful<br /> exploitation may allow interception or modification of communication between<br /> affected devices and cloud controllers.
