CVE-2026-75577 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. Cudy TR3000 before 2.5.42 contains a command injection vulnerability that allows authenticated administrators to execute commands as root by storing a malicious WireGuard private key. Attackers can save a private_key containing $() shell substitution and call the vpn.export_conf method on the /cgi-bin/luci/rpc/app JSON-RPC endpoint, which passes the key to a wg pubkey shell command.. EPSS estimates a 2.43% chance of exploitation in the next 30 days.
