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.","epss":{"date":"2026-11-03","percentile":0.2415,"score":0.00312},"exploits":[],"kev":null,"metrics":[{"score":9.8,"severity":"critical","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},{"score":9.8,"severity":"critical","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793730785170,"publishedAt":1793680989501,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b8a7a925-2b9e-43bc-b649-c7ec518e063c?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://www.acf-extended.com/changelog"},{"source":"security@wordfence.com","tags":[],"url":"https://www.acf-extended.com/changelog"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b8a7a925-2b9e-43bc-b649-c7ec518e063c?source=cve"}],"remediation":[],"revision":"dc6780fe07fa5c5c7fcf7da8ecdfe5a56de63aea8621245f22df6768c2f2ad53","sources":[{"modifiedAt":1793730785170,"name":"CNA: Wordfence","retrievedAt":1793732965216,"url":"https://www.cve.org/CVERecord?id=CVE-2026-120534"},{"modifiedAt":1793683112140,"name":"NVD","retrievedAt":1793686583105,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-120534"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793732986548,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-120534"}],"ssvc":{"assessedAt":1793728504158,"automatable":"yes","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"Advanced Custom Fields: Extended PRO <= 0.9.2.6 - Unauthenticated Remote Code Execution via Dynamic Render Field Type","updatedAt":1793732986548}
