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.

An issue was discovered in function scanallsubs in src/sbbs3/scansubs.cpp in Synchronet BBS, which may allow attackers to view sensitive information due to an uninitialized value.
