Better Auth v1.7.1

better-auth

Bug Fixes

• Added native database transaction support to test instances for PostgreSQL and MySQL.
• Updated bundled dependencies (jose, nanostores, noble crypto packages, SimpleWebAuthn) to their latest compatible releases, with no changes required to existing projects.

For detailed changes, see CHANGELOG

@better-auth/scim

Bug Fixes

• Fixed case-insensitive parsing of string Boolean values for SCIM User active and the primary sub-attribute of emails, phoneNumbers, addresses, roles, and entitlements at the HTTP ingress, improving Microsoft Entra interoperability.
• Added an optional SCIM-owned connection and credential catalog: configure managedConnections to allow trusted server code to create runtime tenant connections and issue, rotate, and revoke bearer credentials through server-only auth.api methods, without a code-defined connection or an application-owned verifier.
• Fixed an issue where trusted server code could not retain a terminal connection binding before a dynamic SCIM connection's first authenticated request when supplying a provisioning domain during decommissioning.

For detailed changes, see CHANGELOG

@better-auth/sso

Bug Fixes

• Fixed SSO provider registration to allow reusing a SCIM connection ID, as SCIM connections no longer participate in the authentication provider namespace.
• Fixed SAML assertion signature verification to validate signatures on the raw assertion instead of trusting an already-parsed response, and enforced signing policy and size limits on SP metadata. wantAssertionsSigned now correctly controls whether the SP requires signed assertions, matching real-world IdP signing behavior.

For detailed changes, see CHANGELOG

@better-auth/cimd

Bug Fixes

• Fixed Client ID Metadata Document caching to follow shared-cache freshness rules: the plugin now prefers s-maxage over max-age and Expires, honors s-maxage=0, conditionally revalidates with ETag or Last-Modified, and treats invalid or duplicate freshness directives as immediately stale. Concurrent refreshes now converge on a single client-resource link instead of failing on a unique constraint.

For detailed changes, see CHANGELOG

@better-auth/kysely-adapter

Bug Fixes

• Fixed native adapter transactions for raw database instances (better-sqlite3, node:sqlite, bun:sqlite, mysql2, pg) passed directly as database, matching the behavior of the explicit { db }/{ dialect } config shapes. Plugins requiring native transactions (such as @better-auth/scim) now work correctly when using the quickstart database: new Database(...) form.

For detailed changes, see CHANGELOG

@better-auth/oauth-provider

Bug Fixes

• Fixed scope error responses so MCP clients now receive a 403 with an RFC 6750 insufficient_scope WWW-Authenticate challenge naming every missing scope, allowing clients to request all needed scopes in a single authorization request.

For detailed changes, see CHANGELOG

auth

Bug Fixes

• Fixed the CLI to refuse adding required columns without default values to already-populated tables (#10863)
