AI-suggested
Upgrade honojs node-server to version 1.19.18 or later if using the 1.x branch, or to version 2.1.6 or later if using the 2.x branch. These versions contain the fix for this interpretation conflict vulnerability. No other mitigation is required as the issue is resolved in these releases.
Description
A vulnerability in honojs node-server versions prior to 1.19.18 and from 2.0.0 up to 2.1.6 allows an unauthenticated client to bypass certain upstream path-based access controls. This occurs because the server passes a raw request-target containing backslashes to the WHATWG URL parser, which treats backslashes as path separators and normalizes the path differently than upstream components. This mismatch can permit access to routes that upstream components intended to block. The issue is fixed in versions 1.19.18 and 2.1.6.
