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." } ], "title": "Forminator Forms <= 1.56.1 - Unauthenticated Arbitrary File Upload via Forged Upload Field Configuration", "references": [ { "url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/263ac05d-f1ca-46e3-a43e-3b45eb8066d4?source=cve" }, { "url": "https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/fields/upload.php#L552" }, { "url": "https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/modules/custom-forms/front/front-action.php#L2767" }, { "url": "https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/modules/custom-forms/front/front-action.php#L738" }, { "url": "https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/helpers/helper-fields.php#L3425" }, { "url": "https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/library/abstracts/abstract-class-field.php#L2308" }, { "url": "https://plugins.trac.wordpress.org/browser/forminator/tags/1.55.1/admin/classes/class-admin-ajax.php#L1196" } ], "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": "daroo" } ], "timeline": [ { "time": "2026-07-14T15:25:05.000Z", "lang": "en", "value": "Vendor Notified" }, { "time": "2026-08-17T16:39:51.000Z", "lang": "en", "value": "Disclosed" } ] }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-08-18T15:26:32.093298Z", "id": "CVE-2026-15748", "options": [ { "Exploitation": "none" }, { "Automatable": "yes" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-08-18T15:28:02.730Z" } } ] } }
