vLLM thanks Chainguard for disclosing vulnerabilities found with a Mythos-based harness

vLLM thanks Chainguard for identifying and responsibly disclosing security vulnerabilities in the project, according to a post from vLLM's X account on October 13, 2026. vLLM says it builds the project with production use and security in mind and credits partners such as Chainguard for making it more secure.

Chainguard says it built a harness around Mythos to find vulnerabilities in open source systems and published the first disclosure from that work. The vLLM post does not give the number, severity or fix status of the vulnerabilities.
