CVE-2026-66065

Q00 · ouroboros

Q00 Ouroboros versions before 0.42.1 are vulnerable to code injection and unauthorized configuration changes due to improper validation of user-defined policies.

Executive summary

Q00 Ouroboros versions prior to 0.42.1 contain a code injection vulnerability that allows an attacker to manipulate system policies and execute arbitrary code.

Vulnerability

The application fails to properly constrain behavior and validate external inputs, leading to CWE-15 (External Control of System Configuration) and CWE-94 (Code Injection), which can be triggered by an attacker with the ability to influence agent policies.

Business impact

Successful exploitation allows an attacker to inject malicious code into the AI coding agent runtime, potentially leading to unauthorized system access, data theft, or the execution of malicious tasks. With a CVSS score of 8.4, this vulnerability poses a high risk to the development environment and any systems integrated with these agents.

Remediation

Immediate Action: Update Ouroboros to version 0.42.1 or later immediately.

Proactive Monitoring: Audit existing AI agent policies for unauthorized modifications and monitor agent execution logs for suspicious code execution patterns.

Compensating Controls: Isolate the Ouroboros runtime in a restricted environment with limited network access to minimize the impact of a potential code injection.

Exploitation status

Public Exploit Available: Unknown.

Analyst recommendation

The severity of code injection vulnerabilities in an AI agent runtime necessitates an immediate update to version 0.42.1. Administrators should ensure that all instances are patched to prevent potential compromise of the automated development pipeline.
