Description
The Better Post & Filter Widgets for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Repeater dynamic tag's 'toggle_title_tag' and 'tab_title_tag' settings in all versions up to, and including, 1.9.1 due to insufficient input sanitization and output escaping. The settings were output as HTML tag names after only esc_attr, without being checked against an allowlist. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
