In versions 0.288.4 through 0.315.3, Strawberry's bundled GraphiQL template wrote values from the GraphiQL headers editor into the browser URL query string. If a user entered a sensitive header, such as `Authorization: Bearer <token>`, the value could become visible in browser history, copied links, and server/proxy/CDN access logs after a page reload or shared request. Version 0.315.4 patches the issue.","published":"2026-06-04T14:09:03.394Z","modified":"2026-08-12T03:51:45.950928484Z","cvss":{"score":3.1,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N"},"epss":{"score":0.00218,"percentile":0.12535,"asOf":"2026-08-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"strawberry-graphql","fixedVersion":"0.315.4"}],"fix":{"url":"https://github.com/strawberry-graphql/strawberry/commit/9315ef80a621ae50ca0bc5c82f560ca4ee7e47a9","label":"strawberry-graphql/strawberry@9315ef8"},"references":[{"type":"WEB","url":"https://github.com/strawberry-graphql/strawberry/releases/tag/0.315.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45739.json"},{"type":"ADVISORY","url":"https://github.com/strawberry-graphql/strawberry/security/advisories/GHSA-x97m-qp5c-w9xj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45739"},{"type":"REPORT","url":"https://github.com/strawberry-graphql/strawberry/issues/4398"},{"type":"FIX","url":"https://github.com/strawberry-graphql/strawberry/commit/9315ef80a621ae50ca0bc5c82f560ca4ee7e47a9"},{"type":"FIX","url":"https://github.com/strawberry-graphql/strawberry/pull/2842"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:45.950928484Z"}}
