{"cve":"CVE-2026-67329","nvd":{"published":"2026-08-01T13:17:03.523","modified":"2026-10-23T23:10:00.157","status":"Deferred","description":"@better-auth/stripe versions >= 1.4.11 and < 1.6.21, and >= 1.7.0-beta.0 and < 1.7.0-beta.10, contain an authorization bypass in organization subscription actions. The middleware validates the organization ID taken from the request query string against the authorizeReference callback, but the handler reads the organization ID only from the request body and falls back to the caller's active organization from their session. When these differ, an authenticated member of multiple organizations can perform subscription actions (cancel, change plan, restore, billing portal access) against an organization they belong to but should not manage, and can access another organization's billing details including payment methods, invoices, and subscription state.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","score":7.1},"cwes":["CWE-639"],"references":["https://github.com/better-auth/better-auth/security/advisories/GHSA-h3rm-78g3-j7cp","https://www.vulncheck.com/advisories/better-auth-stripe-before-authorization-bypass-via-organization-subscription"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-67329","score":0.00313,"percentile":0.23986,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-h3rm-78g3-j7cp","url":"https://osv.dev/vulnerability/GHSA-h3rm-78g3-j7cp","summary":"@better-auth/stripe: cross-organization billing tampering in organization subscription actions","modified":"2026-08-02T03:56:44.913611821Z","packages":[{"ecosystem":"npm","name":"@better-auth/stripe","purl":"pkg:npm/%40better-auth/stripe","ranges":[">=1.4.11 <1.6.21"],"fixed":["1.6.21"]},{"ecosystem":"npm","name":"@better-auth/stripe","purl":"pkg:npm/%40better-auth/stripe","ranges":[">=1.7.0-beta.0 <1.7.0-beta.10"],"fixed":["1.7.0-beta.10"]}]}],"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).
