{"id":"CVE-2026-39371","summary":"RedwoodSDK has a CSRF vulnerability in server function dispatch via GET requests","details":"RedwoodSDK is a server-first React framework. From 1.0.0-beta.50 to 1.0.5, erver functions exported from \"use server\" files could be invoked via GET requests, bypassing their intended HTTP method. In cookie-authenticated applications, this allowed cross-site GET navigations to trigger state-changing functions, because browsers send SameSite=Lax cookies on top-level GET requests. This affected all server functions -- both serverAction() handlers and bare exported functions in \"use server\" files. This vulnerability is fixed in 1.0.6.","aliases":["GHSA-x8rx-789c-2pxq"],"modified":"2026-07-08T08:11:24.000735030Z","published":"2026-04-07T19:28:30.941Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-352"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39371.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39371.json"},{"type":"ADVISORY","url":"https://github.com/redwoodjs/sdk/security/advisories/GHSA-x8rx-789c-2pxq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39371"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/redwoodjs/sdk","events":[{"introduced":"bc3e1a20d3e3dcb084118e68a5b9d7ea17351251"},{"fixed":"06bc739bbc1a074d5e647f362cfce4193d6ba03e"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:redwoodjs:redwoodsdk:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.0.0-beta.50"},{"fixed":"1.0.6"},{"introduced":"1.0.1"}]}}],"versions":["v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v1.0.0-beta.58","v1.0.0-beta.57","v1.0.0-beta.56","community-v0.1.2","v1.0.0-beta.55","v1.0.0-beta.54","v1.0.0-beta.53","v1.0.0-beta.52","v1.0.0-beta.51","community-v0.1.1","community-v0.1.0","v1.0.0-beta.50"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-39371.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H"}]}
