The Passwords Manager plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'pms_save_setting' and 'post_new_pass' AJAX actions in all versions up to, and including, 1.4.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the plugins settings and add passwords.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
