CVE-2026-24887
📋 TL;DR
CVE-2026-24887 is a command injection vulnerability in Claude Code that allows bypassing confirmation prompts to execute arbitrary commands via the find command. This affects users of Claude Code versions before 2.0.72 who process untrusted content. Attackers could execute malicious commands if they can inject content into Claude Code's context window.
💻 Affected Systems
- Claude Code
📦 What is this software?
Claude Code by Anthropic
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the Claude Code process, potentially leading to complete system compromise, data theft, or lateral movement.
Likely Case
Limited command execution within the user's context when processing maliciously crafted content from untrusted sources.
If Mitigated
No impact if proper input validation and sandboxing are implemented, or if untrusted content is never processed.
🎯 Exploit Status
Exploitation requires the ability to inject untrusted content into Claude Code's context window, which typically requires some level of user interaction or compromised input sources.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.0.72
Vendor Advisory: https://github.com/anthropics/claude-code/security/advisories/GHSA-qgqw-h4xq-7w8w
Restart Required: Yes
Instructions:
1. Update Claude Code to version 2.0.72 or later. 2. Restart the Claude Code application or service. 3. Verify the update was successful by checking the version.
🔧 Temporary Workarounds
Disable command execution features
allTemporarily disable or restrict Claude Code's ability to execute system commands through configuration.
Check Claude Code documentation for command execution settings
Input validation and sanitization
allImplement strict input validation to prevent untrusted content from reaching Claude Code's command parsing.
🧯 If You Can't Patch
- Restrict Claude Code to only process trusted content from verified sources.
- Run Claude Code in a sandboxed environment with minimal privileges to limit potential damage from exploitation.
🔍 How to Verify
Check if Vulnerable:
Check Claude Code version - if it's below 2.0.72, the system is vulnerable.Check Version:
Check Claude Code's about/help menu or configuration files for version information.Verify Fix Applied:
Confirm Claude Code version is 2.0.72 or higher and test that command execution prompts cannot be bypassed.📡 Detection & Monitoring
Log Indicators:
- Unexpected command executions from Claude Code process
- Failed confirmation prompt bypass attempts
- Unusual find command usage patterns
Network Indicators:
- Outbound connections from Claude Code to unexpected destinations
- Command and control traffic originating from Claude Code host
SIEM Query:
Process execution where parent_process contains 'claude' AND command_line contains 'find' with suspicious arguments
