{"id":"CVE-2026-33732","aliases":["GHSA-p36q-q72m-gchr"],"url":"https://o3.security/vulnerability/CVE-2026-33732","summary":"srvx is vulnerable to middleware bypass via absolute URI in request line","details":"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.","published":"2026-03-26T17:21:15.709Z","modified":"2026-07-15T01:48:53.633440412Z","cvss":{"score":4.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"srvx","fixedVersion":"0.11.13"}],"fix":{"url":"https://github.com/h3js/srvx/commit/de0d69901c357f36a39b7e13eebef6c930652baa","label":"h3js/srvx@de0d699"},"references":[{"type":"WEB","url":"https://github.com/h3js/srvx/releases/tag/v0.11.13"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33732.json"},{"type":"ADVISORY","url":"https://github.com/h3js/h3/security/advisories/GHSA-p36q-q72m-gchr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33732"},{"type":"FIX","url":"https://github.com/h3js/srvx/commit/de0d69901c357f36a39b7e13eebef6c930652baa"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:53.633440412Z"}}
