RCE in Coderider-Kilo Coderider

CVE-2026-30302

The command auto-approval module in CodeRider-Kilo contains an OS Command Injection vulnerability, rendering its whitelist security mechanism ineffective. The vulnerability stems from the incorrect use of an incompatible command parser (the Unix-based shell-quote library) to analyze commands on the Windows platform, coupled with a failure to correctly handle Windows CMD-specific escape sequences (^). Attackers can exploit this discrepancy between the parsing logic and the execution environment by constructing payloads such as git log ^" & malicious_command ^". The CodeRider-Kilo parser is deceived by the escape characters, misinterpreting the malicious command connector (&) as being within a protected string argument and thus auto-approving the command. However, the underlying Windows CMD interpreter ignores the escaped quotes, parsing and executing the subsequent malicious command directly. This allows attackers to achieve arbitrary Remote Code Execution (RCE) after bypassing what appears to be a legitimate Git whitelist check.
