Summary
The Sympl Repeater for ACF and Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via ACF repeater field values in all versions up to, and including, 2.3. This is due to insufficient input sanitization and output escaping in the symp_arfe_replace_content() function, which uses str_replace() to substitute raw ACF field values (retrieved via get_field()) directly into Elementor-rendered HTML without any escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Risk Assessment
The risk involves potential execution of malicious scripts in the victim's browser, which could lead to session theft, redirects to malicious sites, or theft of sensitive data.
Recommendation
It is recommended to immediately update the Sympl Repeater for ACF and Elementor plugin to the latest available version that fixes this vulnerability. Also, review and remove any suspicious content from ACF repeater fields.
