CVE-2026-30313 identifies a critical OS command injection vulnerability in the command auto-approval module of DSAI-Cline. The module attempts to secure command execution by maintaining a whitelist of allowed commands and filtering out dangerous shell operators such as semicolons (;), logical AND (&&), logical OR (||), pipes (|), and command substitution patterns. However, the filtering mechanism relies on string-based parsing that does not account for raw newline characters embedded within the input commands. An attacker can exploit this by inserting a literal newline character between a whitelisted command and a malicious command payload. For example, a crafted input like "git log\nmalicious_command" is interpreted by the PowerShell interpreter as two separate commands executed sequentially. The system's auto-approval module incorrectly treats the entire input as a safe whitelisted command due to the newline bypass, thus approving and executing the malicious command without any user interaction or authentication. This results in remote code execution (RCE) on the affected system. The vulnerability is severe because it completely undermines the whitelist security mechanism, allowing arbitrary command execution. Although no known exploits have been reported in the wild, the flaw is straightforward to exploit given knowledge of the input validation logic and the use of PowerShell as the command interpreter. The vulnerability affects all versions of DSAI-Cline that implement this flawed command auto-approval logic. No patches or mitigations have been officially released at the time of publication.

The impact of CVE-2026-30313 is significant for organizations using DSAI-Cline with the vulnerable command auto-approval module. Successful exploitation allows remote attackers to execute arbitrary OS commands with the privileges of the affected application or user context, potentially leading to full system compromise. This can result in unauthorized data access, data modification or deletion, installation of persistent malware, lateral movement within networks, and disruption of critical services. Since the vulnerability bypasses whitelist protections and requires no user interaction or authentication, it greatly increases the attack surface and risk of automated exploitation. Organizations relying on DSAI-Cline for automation or command execution in sensitive environments are particularly at risk. The lack of current known exploits provides a window for proactive mitigation, but the ease of exploitation and severity of impact make this a critical threat.

1. Immediately disable or restrict the use of the command auto-approval module in DSAI-Cline until a secure patch is available. 2. Implement input validation that properly handles and sanitizes all control characters, including raw newline characters, before command approval. 3. Replace string-based parsing with a more robust command parsing approach that tokenizes input and explicitly rejects multi-command sequences separated by newlines or other separators. 4. Employ strict allowlisting at the application logic level, verifying commands against a predefined set of safe commands without relying solely on string matching. 5. Run DSAI-Cline with the least privilege necessary to limit the impact of potential command execution. 6. Monitor logs and command execution outputs for suspicious multi-command inputs or unexpected command sequences. 7. Apply network segmentation and firewall rules to restrict access to systems running DSAI-Cline. 8. Stay alert for official patches or updates from the vendor and apply them promptly once available. 9. Conduct security audits and penetration testing focusing on command injection vectors in automation tools. 10. Educate developers and administrators about the risks of improper input sanitization and command injection.
