{"id":"CVE-2026-25149","aliases":["GHSA-92j7-wgmg-f32m"],"url":"https://o3.security/vulnerability/CVE-2026-25149","summary":"Qwik City Open Redirect via fixTrailingSlash","details":"### Summary\n\n**Description**\nAn Open Redirect (CWE-601) vulnerability in Qwik City's default request handler middleware allows a remote attacker to redirect users to arbitrary protocol-relative URLs. Successful exploitation permits attackers to craft convincing phishing links that appear to originate from the trusted domain but redirect the victim to an attacker-controlled site. This affects qwik-city before version 1.19.0. This has been patched in qwik-city version 1.19.0.\n\n### Impact\nQwik City automatically applies the `fixTrailingSlash` middleware to page routes to ensure URL consistency.  This vulnerability impacts all Qwik City applications deployed to runtimes that have a catch-all path to match arbitrary domains and that do not automatically normalize URL paths (e.g. Bun).\n\nExploitation allows an attacker to craft links that trigger a 301 redirect to arbitrary protocol-relative URLs. Browsers interpret this Location header as a protocol-relative URL, redirecting the user to attacker-controlled domains. This can enable phishing attacks and token theft among other common open redirect exploits.\n\n### Patches\nThis has been patched in qwik-city version 1.19.0. Users are strongly encouraged to update to the latest available release.","published":"2026-02-03T21:11:55.902Z","modified":"2026-10-28T02:30:53.825849506Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@builder.io/qwik-city","fixedVersion":"1.19.0"}],"fix":{"url":"https://github.com/QwikDev/qwik/commit/9959eab30a3ad9cc03689eaa080fcfbc33df71ed","label":"QwikDev/qwik@9959eab"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25149.json"},{"type":"ADVISORY","url":"https://github.com/QwikDev/qwik/security/advisories/GHSA-92j7-wgmg-f32m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25149"},{"type":"FIX","url":"https://github.com/QwikDev/qwik/commit/9959eab30a3ad9cc03689eaa080fcfbc33df71ed"},{"type":"PACKAGE","url":"https://github.com/QwikDev/qwik"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:53.825849506Z"}}
