Wordapp <= 1.6.0 - Authorization Bypass through Use of Insufficiently Unique Cryptographic Signature

9.8 Critical

The Wordapp plugin for WordPress is vulnerable to authorization bypass due to an use of insufficiently unique cryptographic signature on the 'wa_pdx_op_config_set' function in versions up to, and including, 1.6.0. This makes it possible for unauthenticated attackers to the plugin to change the 'validation_token' in the plugin config, providing access to the plugin's remote control functionalities, such as creating an admin access URL, which can be used for privilege escalation.
