Technical details

An authorization bypass vulnerability exists in Parse Server's handling of HTTP Range requests. When using storage adapters that support streaming (such as the default GridFS adapter), ranged requests fail to invoke the 'afterFind(Parse.File)' trigger and its associated validators. This allows remote attackers to bypass security logic like 'requireUser' or custom authorization triggers to access restricted files. The vulnerability is exploited via specially crafted HTTP Range headers during file download requests. Patches are available in versions 8.6.71 and 9.7.1-alpha.1.
