What is CVE-2026-10570?
CVE-2026-10570 is a medium-severity cross-site scripting vulnerability in idocoh Sympl Repeater for ACF and Elementor, published on 8 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-79
