A major xAI API key leak has exposed private large language models,raising serious data security concerns for SpaceX,Tesla,and X. For two months, the leaked key granted access to internal AI models, potentially compromising sensitive data, as reported by KrebsOnSecurity. Experts like Philippe Caturegli warn of the risks, highlighting weak key management that could lead to prompt injection and supply chain attacks.

xAI API Key Leak Exposes Private LLMs, Raising Data Security Concerns
Updated May 29, 2025
A leaked API key at Elon Musk’s AI firm, xAI, potentially exposed private large language models (LLMs) for two months, according to KrebsOnSecurity.The exposure could have allowed unauthorized access to custom-built AI models used with internal data from spacex, Tesla, and X.
Philippe Caturegli, the “chief hacking officer” at Seralysis, first publicized the xAI API credential leak found in a github repository. GitGuardian, a firm specializing in detecting exposed secrets, also discovered the leak. Eric Fourrier of GitGuardian said the exposed key provided access to unreleased versions of Grok, xAI’s AI chatbot, and at least 60 fine-tuned and private LLMs.
GitGuardian alerted xAI to the exposed API key in early March, but the key remained active until late April, when GitGuardian directly notified xAI’s security team. xAI then directed gitguardian to report the issue via HackerOne, its bug bounty program. Shortly after, the repository containing the API key was removed from GitHub.
Fourrier noted that some internal LLMs appeared to be fine-tuned using SpaceX and Tesla data. He emphasized that a Grok model fine-tuned with SpaceX data was not intended for public exposure. xAI did not respond to requests for comment.
Carole Winqwist, chief marketing officer at GitGuardian, warned that unauthorized access to private llms could be disastrous. She said attackers could exploit the access for prompt injection, model manipulation, or supply chain attacks.
“The fact that this key was publicly exposed for two months and granted access to internal models is concerning,” Caturegli said. “This kind of long-lived credential exposure highlights weak key management and insufficient internal monitoring, raising questions about safeguards around developer access and broader operational security.”
The xAI incident follows reports about Musk’s Department of Government Efficiency (DOGE) using AI tools with sensitive government records. The washington Post reported that DOGE officials were feeding Education Department data into AI tools to analyze programs and spending. Reuters reported that DOGE is using AI to monitor federal employees’ communications.
What’s next
While there is no evidence that the exposed xAI API key allowed access to government or user data, caturegli cautioned that the private models were likely trained on proprietary data.This raises concerns about potential exposure of internal advancement details from xAI,X,and SpaceX. the incident underscores the importance of robust key management and internal monitoring to prevent unauthorized access to sensitive AI models and data.
