CVE-2026-61426 in PraisonAI
Summary
by MITRE • 07/11/2026
PraisonAI before 1.7.3 contains an insecure default configuration that binds to all interfaces with no API key requirement and wildcard CORS. Unauthenticated attackers can call GET /api/agents to read agent instructions and system prompts, or POST /api/chat to invoke agents without authentication.

The PraisonAI software presents a critical security vulnerability through its insecure default configuration that exposes sensitive system components to unauthenticated access. This flaw exists in versions prior to 1.7.3 where the application binds to all network interfaces without requiring any form of authentication or authorization. The vulnerability stems from the application's default settings that fail to implement proper access controls, creating an attack surface that allows malicious actors to exploit the system without any credentials. The configuration exposes API endpoints that should be protected behind authentication mechanisms, fundamentally compromising the security posture of the application.
The technical implementation of this vulnerability involves multiple interconnected weaknesses that collectively create a dangerous exposure. The application's default binding to all interfaces means that any network interface on the host system can receive requests, bypassing network-level access controls. Additionally, the absence of API key requirements removes any layer of authentication verification for accessing core functionality. The wildcard CORS configuration further amplifies the risk by allowing cross-origin requests from any domain, which can be exploited through malicious web pages or scripts to access the application's API endpoints. This combination creates a perfect storm where attackers can both discover sensitive system information and execute commands without proper authorization.
The operational impact of this vulnerability extends beyond simple data exposure to encompass full system compromise potential. Attackers can retrieve agent instructions and system prompts through GET requests to the /api/agents endpoint, gaining valuable intelligence about how the AI agents function and what they are designed to accomplish. This information could be used to craft more sophisticated attacks or understand the system's operational parameters. The ability to invoke agents through POST requests to /api/chat without authentication means that attackers can actively manipulate the system's behavior, potentially executing arbitrary commands or causing unintended actions within the application environment. This represents a complete breakdown of access control mechanisms and allows for both reconnaissance and active exploitation phases.
Security professionals should implement immediate mitigations to address this vulnerability by configuring proper authentication mechanisms and restricting API endpoint access. The recommended approach includes enforcing API key requirements for all endpoints, implementing strict CORS policies that limit origins to trusted domains only, and configuring the application to bind to specific network interfaces rather than all interfaces. Organizations must also ensure that default configurations are reviewed and hardened before deployment, following security best practices outlined in standards such as CWE-284 which addresses improper access control and CWE-346 which covers origin validation failures. The vulnerability demonstrates the critical importance of principle of least privilege and proper configuration management as outlined in various cybersecurity frameworks including those referenced in the ATT&CK framework where such misconfigurations can lead to initial access and privilege escalation opportunities for adversaries.
This vulnerability highlights fundamental security gaps that organizations must address through comprehensive security testing and configuration reviews. The insecure default settings represent a failure in secure by design principles, where applications should not expose functionality without proper authentication mechanisms. The attack surface created by this flaw allows for both information disclosure and command execution capabilities, making it particularly dangerous for environments where the application might be accessible from untrusted networks. Organizations should implement continuous monitoring to detect unauthorized access attempts and ensure that all default configurations are reviewed against security baselines before deployment. Regular security assessments and penetration testing can help identify similar misconfigurations in other applications and systems within the organization's infrastructure, ensuring a comprehensive approach to vulnerability management and risk mitigation.
