What it is

The wpShopGermany IT-RECHT KANZLEI WordPress plugin before 2.4 does not generate its API authentication token securely, deriving it from data the requester controls and creating it as a side effect of the check that is supposed to validate it, allowing unauthenticated attackers to predict the token and use the access it grants to write arbitrary files, leading to remote code execution.
