{"cve":"CVE-2026-15748","nvd":{"published":"2026-08-18T06:16:40.670","modified":"2026-10-22T22:10:00.250","status":"Deferred","description":"The Forminator Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.56.1 via the handle_file_upload function. This is due to insufficient file type validation in handle_file_upload, where the dangerous-extension blocklist performs exact-key matching that is bypassed by pipe-alternative MIME type keys, combined with a public submission handler that trusts attacker-controlled upload field configuration injected via a forged Select field value. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-434"],"references":["https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/admin/classes/class-admin-ajax.php#L1196","https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/abstracts/abstract-class-field.php#L2308","https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/fields/upload.php#L552","https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/helpers/helper-fields.php#L3425","https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/modules/custom-forms/front/front-action.php#L2767"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-15748","score":0.04088,"percentile":0.90649,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
