CVE-2026-33732: srvx is a universal server based on web standards
CVE-2026-33732 is a medium-severity flaw (CVSS 4.8) affecting srvx. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
