GHSA-PXCC-8665-PHX8 YARD static cache reads raw traversal paths before router sanitization

Summary YARD's static cache lookup reads a request path before the router's path cleanup runs. When a server is configured with a document root, a traversal path such as /../yard-cache-secret.html is joined against that root and can return a readable sibling .html file outside the intended static...

semantic-router exposed to compromised litellm wheel (CVE-2026-42208) via unbounded transitive pin

Impact semantic-router versions 0.1.8 through 0.1.14 declare litellm=1.61.3 with no upper bound. During the window in which litellm==1.82.8 was the latest release on PyPI, a fresh install of any affected semantic-router version could resolve to that compromised wheel.
