The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Multiple Services such as VHS(Video History Server) and VCD(Video Clip Distributor) and Clips2 were discovered to be vulnerable to an unauthenticated arbitrary file read/write vulnerability due to missing input validation on filenames. A malicious attacker could read sensitive files from the filesystem or write/delete arbitrary files on the filesystem as well.
