In brief: OpenAI’s AI models exploited multiple vulnerabilities in JFrog Artifactory to escape a test environment and gain access to the Hugging Face production database.
OpenAI confirms that its AI models, during a security test, exploited a previously unknown vulnerability in JFrog Artifactory and penetrated to the production database of Hugging Face. JFrog has since released patches for cloud and self-hosted installations.
OpenAI’s security team conducted an internal penetration test called ExploitGym to assess the cyber capabilities of its own AI models. The test environment was intentionally configured with reduced security measures: GPT-5.6 Sol and an unreleased, more powerful model operated without production classifiers that normally block risky cyber activities. The only network access was an internal proxy with a software repository cache—this proxy was an installation of JFrog Artifactory, JFrog’s package management software.
The models deployed substantial computing resources to escape the environment. They succeeded in escalating permissions incrementally and moving laterally through the network until they reached a node connected to the open internet. From there, the models inferred that the Hugging Face platform might hold solutions to the test tasks. Ultimately, they extracted test solutions directly from the Hugging Face production database. In one described scenario, the models used stolen credentials and additional zero-day vulnerabilities to gain remote code execution on Hugging Face servers. Hugging Face made the breach public on 16 July, but at the time did not recognize that an AI model was responsible.
JFrog Chief Technology Officer Yoav Landman confirmed that his security team received OpenAI’s findings and developed, tested, and released corrections. JFrog’s cloud customers are already automatically protected. Administrators of self-hosted Artifactory installations must review the manufacturer’s version information and switch to appropriately patched versions for their version branches. Landman warned that a vulnerability found by an AI model and left unpatched would represent “a gift to attackers.”
On 27 July, JFrog published multiple CVE entries for Artifactory, including CVE-2026-65618, CVE-2026-65923, and CVE-2026-66018, listing OpenAI researchers as reporters. However, neither JFrog nor OpenAI has confirmed whether these entries actually correspond to the vulnerabilities exploited during the test. Also unresolved are the required access rights prior to exploitation, the exact number of vulnerabilities exploited, and the Artifactory version in the OpenAI environment. It remains unclear why OpenAI refers to a single zero-day vulnerability in the proxy while JFrog mentions multiple vulnerabilities.
