radare2-mcp <=1.6.0 OS Command Injection via Shell Metacharacter Bypass_CVE-2026-6942

{
    "lastseen": "",
    "description": "radare2-mcp version 1.6.0 and earlier contains an os command injection vulnerability that allows remote attackers to execute arbitrary commands by bypassing the command filter through shell metacharacters in user-controlled input passed to r2_cmd_str(). Attackers can inject shell metacharacters through the jsonrpc interface parameters to achieve remote code execution on the host running radare2-mcp without requiring authentication.",
