better-auth

Bug Fixes

• Added an error code to the change-email-disabled response to help clients identify the rejection reason (#8948)
• Fixed access-control role statement types so predefined organization roles expose only their configured permissions in TypeScript (#9507)
• Fixed the anonymous plugin to correctly call onLinkAccount when email verification triggers auto sign-in (#9548)
• Fixed device authorization to bind pending codes to the verifying session, preventing any authenticated user from approving or denying another user's device code (#9573)
• Fixed a race condition in the magic-link plugin that allowed concurrent requests to mint multiple sessions from the same single-use token (#9572)
• Fixed the oidc-provider and mcp plugins to require client_secret for confidential clients on refresh token grants and use constant-time secret comparison (#9576)
• Hardened oidc-provider and mcp plugins to follow OAuth 2.1: removed "none" from advertised signing algorithms, defaulted plain PKCE off, and rejected incomplete PKCE parameters (#9575)
• Fixed an invitation takeover vulnerability by enabling requireEmailVerificationOnInvitation by default and extending the verification gate to getInvitation and listUserInvitations (#9577)

For detailed changes, see CHANGELOG

@better-auth/oauth-provider

Bug Fixes

• Fixed a race condition in the OAuth authorization-code grant that allowed concurrent token-exchange requests to mint multiple token sets from the same authorization code
• Fixed a race condition in OAuth refresh-token rotation that allowed concurrent requests to fork refresh token families, and added a unique constraint on oauthRefreshToken.token
• Fixed OAuth account linking to require a verified local email before linking an OAuth identity to a local account (#9578)

For detailed changes, see CHANGELOG

@better-auth/core

Bug Fixes

• Fixed an invalid import list in the instrumentation module (#9582)
• Widened advanced.ipAddress.ipv6Subnet to accept any valid IPv6 prefix length (0-128) instead of a narrow set of values (#9545)

For detailed changes, see CHANGELOG

@better-auth/scim

Bug Fixes

• Fixed session cleanup to run when admin, anonymous, or SCIM operations delete a user (#9162)
• Fixed generateSCIMToken to reject providerId values that collide with built-in account providers, preventing tokens from authenticating against unintended accounts (#9579)

For detailed changes, see CHANGELOG

@better-auth/sso

Bug Fixes

• Fixed SSO provider registration to require an org admin or owner role, preventing any organization member from registering providers (#9220)
• Fixed an SSRF vulnerability by validating user-supplied OIDC endpoint URLs against a public-routable host allowlist at provider registration and update (#9574)

For detailed changes, see CHANGELOG

auth

Features

• Added an atomic claimOne adapter primitive for consuming database rows without race conditions (#9560)

Bug Fixes

• Renamed the claimOne adapter primitive to consumeOne and added internalAdapter.consumeVerificationValue for atomically consuming verification rows (#9568)

For detailed changes, see CHANGELOG

@better-auth/api-key

Bug Fixes

• Fixed API key rate-limited responses to return HTTP 429 instead of 401, so clients can distinguish throttling from authentication failures (#9505)

For detailed changes, see CHANGELOG
