CVE-2026-16775

The Smash Balloon Social Post Feed plugin for WordPress contains a vulnerability that allows attackers with contributor-level access or higher to inject malicious scripts into pages. This is due to inadequate filtering of user input and failure to properly prevent the execution of user-submitted code. As a result, when a user accesses the affected page, the injected scripts will run, potentially leading to further security risks. The vulnerability affects all versions of the plugin up to and including 4.9.0.
