CVE-2026-6942: Radare RADARE2 Mcp Server

High severity, CVSS 8.8. EPSS: 3% chance of exploitation in the next 30 days.

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.

Affected products

• Radare RADARE2 Mcp Server: before 1.7.0 (fixed in 1.7.0)
