Overview
The CVE-2025-54377 vulnerability is a serious security flaw identified in the AI-powered coding agent, Roo Code. Roo Code, which lives within user editors, is potent software widely utilized by developers for autonomous coding. The vulnerability is particularly noteworthy because it affects versions 3.23.18 and below of Roo Code, potentially exposing a significant portion of its user base.
The vulnerability arises due to Roo Code’s inability to validate line breaks in its command input, thereby potentially enabling the bypass of the allow-list mechanism. Its implications are severe, ranging from data leakage to system compromise, making it an issue of immediate concern.

How the Exploit Works
The vulnerability lies in the command input validation of Roo Code. Specifically, the software fails to validate line breaks (\n) in its command input. This oversight allows potential bypass of the allow-list mechanism, a security measure designed to prevent unauthorized access.
Without proper parsing or validation, multi-line command injection becomes a possibility. When commands are evaluated for execution, Roo Code only considers the first line or token. This flaw enables attackers to inject additional commands in subsequent lines, potentially leading to unauthorized system access or data leakage.
Conceptual Example Code
Here’s a conceptual example of how an attacker might exploit this vulnerability:
$ echo -e "legitimate_command\nmalicious_command" | roocode executeIn this example, ‘legitimate_command’ would be evaluated and executed by Roo Code. However, due to the vulnerability, the ‘malicious_command’ on the next line would also be executed, potentially causing unauthorized system access or data leakage.
This vulnerability is fixed in version 3.23.19 of Roo Code. Therefore, it is highly recommended that all users upgrade to this version or later. Alternatively, if immediate patching is not feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as a temporary mitigation.
