{"id":"CVE-2026-45739","summary":"Strawberry GraphQL: Default GraphiQL may expose HTTP headers in URLs","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":["GHSA-x97m-qp5c-w9xj","PYSEC-2026-2282"],"modified":"2026-08-12T03:51:45.950928484Z","published":"2026-06-04T14:09:03.394Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45739.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-200","CWE-201"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/strawberry-graphql/strawberry","events":[{"introduced":"85ab96f563f292b2895fe71a216ec83ded614e0e"},{"fixed":"9818abce8195a74eca40d353264659169f2493da"},{"fixed":"9315ef80a621ae50ca0bc5c82f560ca4ee7e47a9"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:strawberry:strawberry_graphql:*:*:*:*:*:python:*:*","extracted_events":[{"introduced":"0.288.4"},{"fixed":"0.315.4"}]}}],"versions":["0.315.3","0.315.2","0.315.1","0.315.0","0.314.3","0.314.2","0.314.1","0.314.0","0.313.0","0.312.4","0.312.3","0.312.2","0.312.1","0.312.0","0.311.3","0.311.2","0.311.1","0.311.0","0.310.2","0.310.1","0.310.0","0.309.0","0.308.3","0.308.2","0.308.1","0.308.0","0.307.1","0.307.0","0.289.0","0.306.0","0.305.0","0.304.0","0.303.1","0.303.0","0.302.0","0.301.0","0.300.0","0.299.0","0.298.1","0.298.0","0.297.0","0.296.2","0.296.1","0.296.0","0.295.0","0.294.0","0.293.0","0.292.0","0.291.3","0.291.2","0.291.1","0.291.0","0.290.0","0.289.8","0.289.7","0.289.6","0.289.5","0.289.4","0.289.3","0.289.2","0.289.1","0.288.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45739.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N"}]}
