CVE-2023-33538
TP-Link Multiple Routers Command Injection Vulnerability. Exploitation in the wild is confirmed by CISA, not predicted.

Risk summary
Actively exploited TP-Link Multiple Routers vulnerability, High severity, CVSS 8.8. Added to the CISA KEV catalog 2025-06-16.
Senserva AI Opinion for CVE-2023-33538
Three TP-Link router families (TL-WR940N, TL-WR841N, TL-WR740N in specific hardware versions) share a command injection flaw in the WlanNetworkRpm component, and the vendor position is that these end-of-life products should simply be discontinued. Its June 2025 KEV entry and 42 percent EPSS reflect ongoing botnet recruitment of abandoned home routers. There is no patch path, only replacement.
Do this: Sweep remote worker and small office sites for these TP-Link models and swap them for supported hardware, since no fix will ever ship.
