{"id":"PYSEC-2026-2282","details":"Strawberry GraphQL is a library for creating GraphQL APIs. 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 \u003ctoken\u003e`, 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.","aliases":["CVE-2026-45739","GHSA-x97m-qp5c-w9xj"],"modified":"2026-07-13T07:15:44.042291538Z","published":"2026-06-04T15:16:54.457Z","references":[{"type":"ADVISORY","url":"https://github.com/strawberry-graphql/strawberry/releases/tag/0.315.4"},{"type":"ADVISORY","url":"https://github.com/strawberry-graphql/strawberry/security/advisories/GHSA-x97m-qp5c-w9xj"},{"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"}],"affected":[{"package":{"name":"strawberry-graphql","ecosystem":"PyPI","purl":"pkg:pypi/strawberry-graphql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.288.4"},{"fixed":"0.315.4"}]}],"versions":["0.288.4","0.289.0","0.289.1","0.289.2","0.289.3","0.289.4","0.289.5","0.289.6","0.289.7","0.289.8","0.290.0","0.291.0","0.291.1","0.291.2","0.291.2.dev1770456508","0.291.2.dev1771437961","0.291.3","0.292.0","0.293.0","0.294.0","0.295.0","0.296.0","0.296.1","0.296.2","0.297.0","0.298.0","0.298.1","0.299.0","0.300.0","0.301.0","0.302.0","0.303.0","0.303.1","0.304.0","0.305.0","0.306.0","0.307.0","0.307.1","0.308.0","0.308.1","0.308.2","0.308.3","0.309.0","0.310.0","0.310.1","0.310.2","0.311.0","0.311.1","0.311.2","0.311.3","0.312.0","0.312.1","0.312.2","0.312.3","0.312.4","0.313.0","0.314.0","0.314.1","0.314.2","0.314.3","0.315.0","0.315.1","0.315.2","0.315.3"],"ecosystem_specific":{},"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/strawberry-graphql/PYSEC-2026-2282.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"}]}
