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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-200","CWE-201"],"references":["https://github.com/strawberry-graphql/strawberry/commit/9315ef80a621ae50ca0bc5c82f560ca4ee7e47a9","https://github.com/strawberry-graphql/strawberry/issues/4398","https://github.com/strawberry-graphql/strawberry/pull/2842","https://github.com/strawberry-graphql/strawberry/releases/tag/0.315.4","https://github.com/strawberry-graphql/strawberry/security/advisories/GHSA-x97m-qp5c-w9xj"],"products":["strawberry:strawberry_graphql"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-45739","score":0.00218,"percentile":0.12315,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-x97m-qp5c-w9xj","url":"https://osv.dev/vulnerability/GHSA-x97m-qp5c-w9xj","summary":"Strawberry GraphQL: Default GraphiQL may expose HTTP headers in URLs","modified":"2026-07-13T07:26:52.672764471Z","packages":[{"ecosystem":"PyPI","name":"strawberry-graphql","purl":"pkg:pypi/strawberry-graphql","ranges":[">=0.288.4 <0.315.4"],"fixed":["0.315.4"]}]},{"id":"PYSEC-2026-2282","url":"https://osv.dev/vulnerability/PYSEC-2026-2282","summary":"","modified":"2026-07-13T07:15:44.042291538Z","packages":[{"ecosystem":"PyPI","name":"strawberry-graphql","purl":"pkg:pypi/strawberry-graphql","ranges":[">=0.288.4 <0.315.4"],"fixed":["0.315.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
