This is due to insufficient validation of form configuration parameters before merging into field settings and passing to call_user_func_array in the render_field method. This makes it possible for unauthenticated attackers to call arbitrary WordPress functions with controlled arguments. Method 1 requires the administrator to enable the non-default 'shortcode_preview' setting for the target form, while Method 2 requires the server environment to lack OpenSSL functions, causing ACF Pro's acf_decrypt to fall back to unverified base64 decoding.","dueDate":"","id":"CVE-2026-120534","kev_catalogs":["vulncheck"],"knownRansomwareCampaignUse":"Unknown","product":"Advanced Custom Fields: Extended PRO","requiredAction":"Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.","severity":"CRITICAL","source":"vulncheck_kev","title":"  Unrestricted Upload of File with Dangerous Type","vendor":"ACF Extended"}
