BOLT is a static analysis tool, part of the LLVM compiler infrastructure, used to verify compiler security hardening options have been applied on a binary.
Thanks to @ostifofficial.bsky.social we've worked since November 2025 to improve it. Check our progress here:

A lack of input sanitization on host header paths in Starlette leads to bypassing auth with a single character across a huge swath of Python LLM infrastructure.
Update to Starlette 1.0.1 as soon as possible and read more about this vulnerability on badhost.org
During a security audit of vLLM managed by OSTIF.org, a bug was discovered through manual analysis by a senior security expert at X41 D-Sec.
