CVE-2025-54377
📋 TL;DR
CVE-2025-54377 is a command injection vulnerability in Roo Code AI coding agent that allows bypassing allow-list restrictions via line break characters. Attackers can smuggle unauthorized commands by injecting newline characters in command input. This affects all users running Roo Code versions 3.23.18 and below.
💻 Affected Systems
- Roo Code AI coding agent
📦 What is this software?
Roo Code by Roocode
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through arbitrary command execution, potentially leading to data theft, ransomware deployment, or complete host takeover.
Likely Case
Limited command execution within the user's context, potentially accessing sensitive files, modifying code, or establishing persistence.
If Mitigated
Commands limited to allow-list functionality only, with no unauthorized execution possible.
🎯 Exploit Status
Exploitation requires user interaction with the Roo Code agent, but the injection technique is simple once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.23.19
Vendor Advisory: https://github.com/RooCodeInc/Roo-Code/security/advisories/GHSA-p278-52x9-cffx
Restart Required: Yes
Instructions:
1. Update Roo Code to version 3.23.19 or later. 2. Restart your editor/IDE. 3. Verify the update completed successfully.
🔧 Temporary Workarounds
Disable command execution
allTemporarily disable Roo Code's command execution features until patched.
Check Roo Code settings for command execution options and disable them
Restrict to trusted sources
allOnly use Roo Code with trusted codebases and avoid unknown or untrusted inputs.
🧯 If You Can't Patch
- Isolate Roo Code usage to development environments with limited network access and minimal privileges.
- Implement strict monitoring of command execution and alert on unusual patterns or unexpected commands.
🔍 How to Verify
Check if Vulnerable:
Check Roo Code version in your editor/IDE settings. If version is 3.23.18 or below, you are vulnerable.Check Version:
Check within your editor's Roo Code extension settings or run: roo --version if CLI is availableVerify Fix Applied:
After updating, verify version is 3.23.19 or higher and test that multi-line command injection is no longer possible.📡 Detection & Monitoring
