    Cross-site Scripting (XSS)

    @better-auth/sso is a SSO plugin for Better Auth

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) through the SAML login pipeline in packages/sso/src/routes/saml-pipeline.ts. An attacker can sign in as another user by sending a SAML response whose AudienceRestriction, bearer Recipient, or Destination is meant for a different service provider but is still accepted during session creation. This lets the attacker obtain a valid session for the victim account; in affected deployments, that can also grant the victim’s organization privileges if the account is an owner or admin.

    Workarounds

    • Leave saml.enableSingleLogout off unless you need single logout.
    • Prefer pre-validated defaultSSO providers for SAML.

    How to fix Cross-site Scripting (XSS)?

    Upgrade @better-auth/sso to version 1.6.21, 1.7.0-beta.10 or higher.
