Summary
The Beaver Builder Page Builder plugin for WordPress up to version 2.10.2.2 is vulnerable to stored cross-site scripting via the Button Code setting in the Button Module. Insufficient input sanitization and output escaping allow authenticated attackers with author-level access to inject arbitrary scripts that execute when a user accesses an injected page.
Risk Assessment
An attacker with author privileges can inject malicious scripts, potentially leading to data theft, session hijacking, or content modification.
Recommendation
Update the Beaver Builder plugin to the latest patched version. Restrict author-level access to trusted users only.
