Highest priority

Known exploited (CISA KEV) first, then by EPSS exploit probability.

CVE-2025-15627, published 2026-08-03. High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days. A cryptographic weakness exists in the Omada adoption protocol. The protocol relies on hard-coded cryptographic keys to establish trust and protect authentication exchanges between controllers and…
CVE-2025-15544, published 2026-08-03. Medium severity, CVSS 5.9. EPSS: 0.3% chance of exploitation in the next 30 days. A cryptographic weakness exists in the Omada device adoption process. During adoption, authentication credentials associated with site management are transmitted using a weak hashing algorithm that…
CVE-2025-15629, published 2026-08-03. High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days. A cryptographic weakness exists in the Omada adoption protocol where session encryption keys used to protect communications between controllers and managed devices may be predictable due to…
CVE-2025-15628, published 2026-08-03. High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days. Affected Omada devices rely on embedded certificates that are shared across deployments to establish trust between controllers and managed devices. An attacker who obtains the embedded…
CVE-2025-15630, published 2026-08-03. Medium severity, CVSS 5.9. EPSS: 0.3% chance of exploitation in the next 30 days. A race condition exists in the cloud-based Omada device adoption process when an attacker may be able to interact with the adoption workflow before a legitimate device completes registration,…
