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.

SAP BTP Security Services Integration Library ([Java] cloud-security-services-integration-library) - versions below 2.17.0 and versions from 3.0.0 to before 3.3.0, allow under certain conditions an escalation of privileges. On successful exploitation, an unauthenticated attacker can obtain arbitrary permissions within the application.

The tagDiv Cloud Library WordPress plugin before 2.7 does not have authorisation and CSRF in an AJAX action accessible to both unauthenticated and authenticated users, allowing unauthenticated users to change arbitrary user metadata, which could lead to privilege escalation by setting themselves as an admin of the blog.
