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"}}]}}
