BlockSpare - Gutenberg Site Builder Blocks & Starter Sites <= 4.2.6 - Incorrect Authorization to Authenticated (Subscriber+) Arbitrary Post Creation

BlockSpare - Gutenberg Site Builder Blocks & Starter Sites <= 4.2.6 - Incorrect Authorization to Authenticated (Subscriber+) Arbitrary Post Creation

The BlockSpare plugin for WordPress is vulnerable to authorization bypass due to incorrect logic in the permission callback in all versions up to, and including, 4.2.6 due to the use of an AND (&&) operator instead of an OR (||) operator. This makes it possible for authenticated attackers, with Subscriber-level access and above, to bypass authorization checks and create arbitrary posts.
