Note: Versions mentioned in the description apply only to the upstream langfuse-2 package and not the langfuse-2 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Vitest is a testing framework powered by Vite. Prior to 3.2.5 and 4.1.0, the Vitest UI/API server on Windows used isFileServingAllowed incorrectly for /vitest_attachment, allowing \?\..\ path traversal to read files outside the project; exposed API write and rerun features such as saveTestFile and rerun could also allow arbitrary script execution. This issue is fixed in versions 3.2.5 and 4.1.0.
