This is due to the function accepting user input and then passing that through call_user_func_array(). This makes it possible for unauthenticated attackers to execute arbitrary code on the server, which can be leveraged to inject backdoors or create new administrative user accounts.","publishedAt":"2025-12-03T06:47:46.730Z","updatedAt":"2025-12-03T14:32:58.739Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["hwk-fr Advanced Custom Fields: Extended"],"affected":[{"vendor":"hwk-fr","product":"Advanced Custom Fields: Extended","defaultStatus":"unaffected","versions":[{"version":"0.9.0.5","status":"affected","lessThanOrEqual":"0.9.1.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/c508cb73-53e6-4ebe-b3d0-285908b722c9?source=cve","https://plugins.trac.wordpress.org/changeset/3400134/acf-extended"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/13xxx/CVE-2025-13486.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-13486","state":"PUBLISHED","datePublished":"2025-12-03T06:47:46.730Z","dateUpdated":"2025-12-03T14:32:58.739Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-11-20T17:33:07.800Z"},"containers":{"cna":{"title":"Advanced Custom Fields: Extended 0.9.0.5 - 0.9.1.1 - Unauthenticated Remote Code Execution in prepare_form","descriptions":[{"lang":"en","value":"The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to Remote Code Execution in versions 0.9.0.5 through 0.9.1.1 via the prepare_form() function.
