Description
The Simple Membership plugin for WordPress is vulnerable to Sensitive Information Exposure via its debug log files in all versions up to, and including, 4.8.7. This is due to the debug and authentication debug logs being written to the publicly accessible plugin directory without access protection, using a file name suffix generated by the time-based, guessable uniqid() function. This makes it possible for unauthenticated attackers to guess the log file names and download logs containing payment notification data and member and login details, provided debug logging is enabled.
