This vulnerability was named CVE-2026-33732. The attack may be initiated remotely. There is no available exploit. Upgrading the affected component is recommended. Detailsinfo A vulnerability classified as problematic has been found in h3js srvx up to 0.11.12. This affects an unknown code block of the component HTTP Request Handler. The manipulation with an unknown input leads to a name resolution vulnerability. CWE is classifying the issue as CWE-706. The product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is: 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. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-33732 since 03/23/2026. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. Upgrading to version 0.11.13 eliminates this vulnerability.
