CVE-2025-15060 Overview
CVE-2025-15060 is a critical command injection vulnerability affecting claude-hovercraft that enables remote code execution without authentication. The vulnerability exists within the executeClaudeCode method, where insufficient validation of user-supplied input allows attackers to inject malicious commands into system calls. This flaw was originally tracked as ZDI-CAN-27785 by the Zero Day Initiative.
Critical Impact
Remote attackers can execute arbitrary code on affected claude-hovercraft installations without authentication, potentially leading to complete system compromise and lateral movement within the network.

Technical Details for CVE-2025-15060
Vulnerability Analysis
This command injection vulnerability (CWE-78) stems from improper handling of user-controlled input within the executeClaudeCode method. The vulnerable code path accepts external input and passes it directly to a system shell without adequate sanitization or validation. Because no authentication is required to reach this functionality, remote attackers can exploit this flaw over the network to gain code execution privileges within the context of the service account running claude-hovercraft.
The network-accessible nature of this vulnerability combined with the lack of authentication requirements significantly increases the attack surface. Successful exploitation grants attackers the ability to execute arbitrary commands, potentially leading to data exfiltration, persistence establishment, or further compromise of connected systems.
Root Cause
The root cause is the absence of proper input validation and sanitization before incorporating user-supplied strings into system call execution. The executeClaudeCode method directly concatenates or interpolates untrusted input into command strings that are then executed by the underlying operating system shell. This classic command injection pattern allows attackers to break out of the intended command context and execute arbitrary commands.
Attack Vector
The attack vector is network-based, requiring no prior authentication. An attacker can craft malicious requests containing shell metacharacters or command separators (such as ;, |, &&, or backticks) within the user-supplied input. When this input reaches the executeClaudeCode method, the injected commands are executed alongside or instead of the intended operation.
The vulnerability can be exploited by sending specially crafted input to the claude-hovercraft service that includes shell command injection payloads. Common injection techniques include command chaining using semicolons, pipe operators for command substitution, or backtick-enclosed commands. For detailed technical information, refer to the Zero Day Initiative Advisory ZDI-26-124.
Detection Methods for CVE-2025-15060
Indicators of Compromise
- Unusual process spawning from the claude-hovercraft service account, particularly shell processes like /bin/sh, /bin/bash, or cmd.exe
- Network connections to unexpected external IP addresses originating from the service process
- Unexpected files created in temporary directories or world-writable locations
- Log entries showing malformed or suspicious input containing shell metacharacters
Detection Strategies
- Monitor system call activity from the claude-hovercraft process for unexpected command execution patterns
- Implement network-level inspection for requests containing common command injection payloads (;, |, &&, backticks, $())
- Deploy endpoint detection rules to identify child process creation from the claude-hovercraft service
- Review application logs for input patterns containing shell escape sequences or command separators
Monitoring Recommendations
- Enable verbose logging on the claude-hovercraft service to capture all incoming requests and their parameters
- Configure SIEM alerts for anomalous process trees originating from the affected service
- Monitor for unauthorized file system modifications in system directories following service requests
- Implement network segmentation monitoring to detect lateral movement attempts following potential exploitation
How to Mitigate CVE-2025-15060
Immediate Actions Required
- Restrict network access to claude-hovercraft services using firewall rules or network segmentation
- Implement web application firewall (WAF) rules to filter requests containing command injection patterns
- Consider temporarily disabling the affected executeClaudeCode functionality if operationally feasible
- Monitor affected systems for signs of compromise while awaiting official patches
Patch Information
Consult the Zero Day Initiative Advisory ZDI-26-124 for the latest patch availability and vendor response information. Apply vendor-supplied security updates as soon as they become available.
Workarounds
- Deploy network-level access controls to limit exposure of the claude-hovercraft service to trusted networks only
- Implement input validation at the network perimeter to block requests containing shell metacharacters
- Run the claude-hovercraft service with minimal privileges using a dedicated service account with restricted permissions
- Consider containerization or sandboxing to limit the impact of potential exploitation
