CVE-2026-33732

srvx is a universal server based on web standards. Prior to version 0.11.13, a pathname parsing discrepancy in srvx's `F

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.
