Vulnerabilities in Open-Source AI Models: A Cybersecurity Warning 2025

As the use of artificial intelligence (AI) and machine learning (ML) expands, so too does the prevalence of vulnerabilities in open-source AI models. From large language models (LLMs) to self-hosted frameworks, vulnerabilities within these systems are opening doors to potential data theft, unauthorized access, and code manipulation. In this article, we delve into recent findings on vulnerabilities in open-source AI models, the implications for users, and proactive measures to mitigate these risks.

Understanding the Landscape of Vulnerabilities in Open-Source AI Models

Recent research reveals a range of vulnerabilities in open-source AI models, impacting widely used tools like ChuanhuChatGPT, Lunary, and LocalAI. Submitted through Protect AI’s Huntr bug bounty platform, these findings underscore the risks involved in using open-source AI without strong security controls. Among the most severe vulnerabilities are issues that enable remote code execution, data manipulation, and unauthorized data access.

Lunary’s Vulnerabilities: A Case Study in Open-Source AI Model Risks

One prominent example of vulnerabilities in open-source AI models lies within Lunary, a toolkit widely used for large language model production:

• CVE-2024-7474 and CVE-2024-7475 (CVSS score: 9.1 each) represent critical vulnerabilities in Lunary’s infrastructure. The first, an Insecure Direct Object Reference (IDOR) vulnerability, allows users to access or delete external data without permission, leading to unauthorized data access. The second is an improper access control vulnerability, giving attackers the ability to alter the system’s SAML configuration. With this access, unauthorized users could potentially gain system control, posing a major threat to data privacy.
• CVE-2024-7473 (CVSS score: 7.5) highlights another example of Lunary’s vulnerabilities. This IDOR vulnerability enables attackers to alter prompts by manipulating a parameter in the system. This is particularly concerning for AI tools, where prompt integrity is critical to output accuracy.

The examples above underscore how critical vulnerabilities in open-source AI models like Lunary can endanger both user data and model reliability.

ChuanhuChatGPT’s Vulnerabilities: Path Traversal and Execution Risks

Another concerning example of vulnerabilities in open-source AI models is found in ChuanhuChatGPT, which has been impacted by a path traversal flaw (CVE-2024-5982, CVSS score: 9.1). This flaw permits attackers to:

• Execute arbitrary code, allowing them to create directories, execute malicious commands, or expose sensitive files within the system.
• Use unchecked file paths as a pathway to access and manipulate system data.

For users and organizations leveraging ChuanhuChatGPT, these vulnerabilities highlight the importance of stringent security protocols to mitigate risks associated with improper file handling.

LocalAI and Timing Attacks: When AI Model Security Lapses

LocalAI, a self-hosted open-source LLM, demonstrates additional forms of vulnerabilities in open-source AI models, including:

• CVE-2024-6983 (CVSS score: 8.8), a vulnerability enabling arbitrary code execution through malicious configurations. By manipulating these configurations, attackers can execute unauthorized commands within the AI model, leading to potentially severe outcomes.
• CVE-2024-7010 (CVSS score: 7.5), a side-channel timing attack vulnerability. This flaw allows attackers to infer valid API keys by analyzing response times, giving unauthorized users access to system resources.

These examples illustrate how vulnerabilities in open-source AI models like LocalAI extend beyond traditional attacks, posing unique security challenges in timing analysis and access control. Ensuring proper validation of configurations and implementing rate-limiting measures are crucial steps to prevent such attacks.

Broader Implications: Other Open-Source AI Model Vulnerabilities

In addition to the models highlighted above, vulnerabilities in open source AI models extend to other popular frameworks. The Deep Java Library (DJL), for example, has a significant vulnerability (CVE-2024-8396, CVSS score: 7.8) related to arbitrary file overwrites within the package’s untar function, creating opportunities for remote code execution. NVIDIA’s NeMo generative AI framework has also been found vulnerable, with a path traversal flaw (CVE-2024-0129, CVSS score: 6.3) that could lead to data tampering if exploited.

Each of these cases serves as a powerful reminder that vulnerabilities in open-source AI models are a widespread and urgent issue. To prevent data breaches and system corruption, users must stay proactive about software updates, patches, and security best practices.

Emerging Tools for Identifying Vulnerabilities in Open-Source AI Models

To address the growing number of vulnerabilities in open-source AI models, new tools like Vulnhuntr are emerging. Developed by Protect AI, Vulnhuntr is an open-source Python static code analyzer designed to detect potential zero-day vulnerabilities in Python-based AI models. This tool leverages AI to:

• Analyze project files in manageable chunks, allowing it to assess the entire call chain from user input to output without overwhelming the model.
• Detect zero-day vulnerabilities by identifying potential security risks throughout the project.

With tools like Vulnhuntr, organizations can automate vulnerability detection and improve the security of their open source AI models.

Jailbreaking AI Models: A Novel Security Concern

The emergence of jailbreaking methods also underscores the complex landscape of vulnerabilities in open source AI models. Mozilla’s 0Day Investigative Network (0Din) recently demonstrated a technique to bypass OpenAI’s ChatGPT safety filters by encoding harmful commands in hexadecimal format and emojis. This type of attack, termed linguistic loophole exploitation, allows attackers to encode malicious commands that appear benign, thereby bypassing AI safeguards.

This exploitation of vulnerabilities in open-source AI models through linguistic loopholes reveals a new security frontier, where even natural language processing models can be manipulated through creative input encoding.
