CVE-2026-10570: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in idocoh Sympl Repeater for ACF and Elementor
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.
AI Analysis
Technical Summary
CVE-2026-10570 is a stored cross-site scripting vulnerability in the Sympl Repeater for ACF and Elementor plugin for WordPress. The issue is caused by the symp_arfe_replace_content() function using str_replace() to insert raw Advanced Custom Fields (ACF) repeater field values into Elementor-generated HTML without proper escaping or sanitization. This allows authenticated attackers with Author-level privileges or above to inject arbitrary JavaScript code into pages, which executes in the context of users viewing those pages. The vulnerability affects all plugin versions up to and including 2.3.
Potential Impact
Successful exploitation allows an authenticated user with Author-level access or higher to inject malicious scripts into pages. These scripts execute in the browsers of users who view the compromised pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability does not affect availability and requires authenticated access, but it compromises confidentiality and integrity of user interactions with affected pages.
Mitigation Recommendations
No official patch or fix has been confirmed or published by the vendor as of the provided data. Users should monitor the vendor advisory for updates. Until a fix is available, restrict Author-level access to trusted users only and consider disabling or replacing the plugin if possible to reduce risk.
