DescriptionGitHub Advisory

Impact

The Pages route and legacy PublicAPI route for resending email verification links return distinguishable responses depending on whether the provided username exists and has an unverified email. This allows an unauthenticated attacker to enumerate valid usernames by observing different redirect targets. The existing emailVerifySuccessOnInvalidEmail configuration option, which is enabled by default and protects the API route against this, did not apply to these routes.

Patches

The email verification resend routes now respect the emailVerifySuccessOnInvalidEmail option. When set to true (the default), both routes redirect to the success page regardless of the outcome, preventing user enumeration.

Workarounds

There is no known workaround to prevent the information disclosure other than upgrading.

AnalysisAI

Email verification resend endpoints in the Pages and legacy PublicAPI routes leak information about valid usernames through distinguishable responses, enabling unauthenticated attackers to enumerate active accounts. The default emailVerifySuccessOnInvalidEmail configuration option, which mitigates this issue, was not applied to these specific routes. A patch is available that extends the protection to both routes.

Technical ContextAI

Information disclosure occurs when an application inadvertently reveals sensitive data to unauthorized actors through error messages, logs, or improper access controls.

RemediationAI

A vendor patch is available — apply it immediately. Implement proper access controls. Sanitize error messages in production. Review logging practices to avoid capturing sensitive data.
