CVE-2026-62312: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in decolua 9router
9Router versions prior to 0.5.2 contain an OS command injection vulnerability that allows a remote authenticated attacker to execute arbitrary code on the host system. This is achieved by bypassing localhost-only route restrictions via the Host header and passing unvalidated arguments to child_process.spawn() through the /api/mcp//sse endpoint. The vulnerability is fixed in version 0.5.2.
AI Analysis
Technical Summary
CVE-2026-62312 is an OS command injection vulnerability in decolua's 9Router product. Versions before 0.5.2 allow a remote authenticated attacker to bypass localhost-only route restrictions by manipulating the Host header. This bypass enables the attacker to send unvalidated arguments to the child_process.spawn() function via the /api/mcp//sse endpoint, resulting in arbitrary code execution on the host operating system. The issue is resolved in version 0.5.2.
Potential Impact
Successful exploitation allows an authenticated remote attacker to execute arbitrary commands on the host operating system, leading to full compromise of the affected system's confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade 9Router to version 0.5.2 or later, where this vulnerability has been fixed. No other official remediation or temporary fixes are indicated. Patch status is confirmed by the vendor advisory stating the fix in 0.5.2.
