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."}],"title":"Advanced Custom Fields: Extended PRO <= 0.9.2.6 - Unauthenticated Remote Code Execution via Dynamic Render Field Type","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b8a7a925-2b9e-43bc-b649-c7ec518e063c?source=cve"},{"url":"https://www.acf-extended.com/changelog"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-434 Unrestricted Upload of File with Dangerous Type","cweId":"CWE-434","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"Tin Pham (TF1T)"},{"lang":"en","type":"finder","value":"Trong Pham (dtro)"},{"lang":"en","type":"finder","value":"Hao Ngo"}],"timeline":[{"time":"2026-07-26T20:21:34.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-14T00:00:00.000Z","lang":"en","value":"Disclosed"}]}}}
