CVE-2026-53513 · Better Auth: Server-side request forgery via unvalidated OIDC endpoints on @better-auth/sso provider registration
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Better Auth is an authentication and authorization library for TypeScript. Prior to 1.6.11, the @better-auth/sso plugin's POST /sso/register and POST /sso/update-provider endpoints accept attacker-controlled oidcConfig.userInfoEndpoint, tokenEndpoint, and jwksEndpoint URLs when skipDiscovery: true is set, store them on the ssoProvider row without origin validation, and fetch them during OIDC callback, allowing non-blind server-side request forgery and possible account linking when trustEmailVerified: true is configured. This issue is fixed in version 1.6.11.
