In addition, password reset link is not invalidated if a logged-in user changes her password. -------- VERSIONS AFFECTED --------------------------------------------------- * Secure Password Hashes (phpass) for Drupal 6.x before 6.x-1.1 * Secure Password Hashes (phpass) for Drupal 5.x before 5.x-1.5 Drupal core is not affected.
