NVD Description

Note: Versions mentioned in the description apply only to the upstream langfuse-3 package and not the langfuse-3 package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

@hono/node-server allows running the Hono application on Node.js. Prior to 1.19.13, a path handling inconsistency in serveStatic allows protected static files to be accessed by using repeated slashes (//) in the request path. When route-based middleware (e.g., /admin/*) is used for authorization, the router may not match paths containing repeated slashes, while serveStatic resolves them as normalized paths. This can lead to a middleware bypass. This vulnerability is fixed in 1.19.13.
