CVE-2026-26185: Directus Affected by User Enumeration via Password Reset Timing Attack

Summary

A timing-based user enumeration vulnerability exists in the password reset functionality. When an invalid reseturl parameter is provided, the response time differs by approximately 500ms between existing and non-existing users, enabling reliable user enumeration.

Details

The password reset endpoint implements a timing protection mechanism to prevent user enumeration; however, URL validation executes before the timing protection is applied. This allows an attacker to distinguish between valid and invalid user accounts based on response timing differences.

Impact

This vulnerability violates user privacy and may facilitate targeted phishing attacks by allowing attackers to confirm the existence of user accounts.
