CVE-2023-1389
TP-Link Archer AX-21 Command Injection Vulnerability. Exploitation in the wild is confirmed by CISA, not predicted.

Risk summary
Actively exploited TP-Link Archer AX21 vulnerability, High severity, CVSS 8.8. Added to the CISA KEV catalog 2023-05-01.
Senserva AI Opinion for CVE-2023-1389
The TP-Link Archer AX21 is a consumer router, and this command injection with a 100% EPSS score is a textbook botnet feeder: exposed home and small-office devices are conscripted en masse for DDoS and proxy duty. For enterprises the risk is indirect but real, since remote employees behind compromised routers have their traffic transiting attacker-controlled hardware. It is rated High Severity (CVSS 8.8) and has been exploited since at least its May 2023 KEV listing.
Do this: Tell remote workers using Archer AX21 routers to apply TP-Link's firmware update, and require VPN with encrypted DNS from home networks.
