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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-352"],"references":["https://github.com/redwoodjs/sdk/security/advisories/GHSA-x8rx-789c-2pxq"],"products":["redwoodjs:redwoodsdk"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-39371","score":0.0021,"percentile":0.11276,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-x8rx-789c-2pxq","url":"https://osv.dev/vulnerability/GHSA-x8rx-789c-2pxq","summary":"RedwoodSDK has a CSRF vulnerability in server function dispatch via GET requests","modified":"2026-04-08T00:27:17.091327Z","packages":[{"ecosystem":"npm","name":"rwsdk","purl":"pkg:npm/rwsdk","ranges":[">=1.0.0-beta.50 <1.0.6"],"fixed":["1.0.6"]}]}],"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).
