Active exploitationNonot in the CISA catalog
Public exploitAvailableProof of concept on GitHub (unverified) · Metasploit module (reliable, widely available exploit)

Due to a reliance on client-side authentication, the WiFi Mouse (Mouse Server) from Necta LLC's authentication mechanism is trivially bypassed, which can result in remote code execution.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
