CVE-2026-46643Public exploit

Command execution via unescaped binary path

Published Jun 10, 2026 · Updated Jun 10, 2026

OS command injection in KNP Labs Snappy before 1.7.1 allows attackers to execute commands via an attacker-influenced POSIX binary path. The command builder tests is_executable() against an already shell-quoted path, so the check fails and the raw binary string reaches the shell. Exploitation requires control over the configured binary string and runs injected commands with the PHP process's privileges.
