CVE-2026-30815Public exploit

Authenticated command execution via OpenVPN restore directives

Published Apr 8, 2026 · Updated Apr 8, 2026

OS command injection in TP-Link Archer AX53 v1.0 firmware before 1.7.1 Build 20260213 allows remote authenticated users to run commands. The OpenVPN init script writes untrusted script-security, client-connect, client-disconnect, and route-up restore values into its configuration for command execution. Administrative web access and adjacent-network reachability are required; execution can alter configuration, disclose sensitive data, and compromise the router.
