Overview
parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js.
Affected versions of this package are vulnerable to Improper Authentication in the LDAP authentication process. An attacker can gain unauthorized access to user accounts by supplying a known directory username with an empty password, which may result in account takeover. This is only exploitable if the LDAP authentication adapter is enabled and the directory allows unauthenticated simple bind (such as Active Directory in its default configuration).
