CVE-2026-33732
MEDIUMsrvx is vulnerable to middleware bypass via absolute URI in request line
Title source: cnaDescription
srvx is a universal server based on web standards. Prior to version 0.11.13, a pathname parsing discrepancy in srvx's `FastURL` allows middleware bypass on the Node.js adapter when a raw HTTP request uses an absolute URI with a non-standard scheme (e.g. `file://`). Starting in version 0.11.13, the `FastURL` constructor now deopts to native `URL` for any string not starting with `/`, ensuring consistent pathname resolution.
