An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-15748 in the wild and no public exploit code.\n\nAffected product: wpmudev Forminator Forms – Contact Form, Payment Form \u0026 Custom Form Builder. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-15748/ (Markdown: https://insights.sbomify.com/CVE-2026-15748/index.md)","id":"CVE-2026-15748","markdown":"https://insights.sbomify.com/CVE-2026-15748/index.md","name":"CVE-2026-15748","record":{"aliases":["GHSA-3p88-69p6-f6mj"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can upload executable files via forged field configurations, leading to remote code execution on WordPress sites using Forminator Forms.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-18","github_poc":3,"max_poc_stars":3,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-18T14:44:00Z","kind":"github_poc","ref":"https://github.com/yora1928/cve-2026-15748","stars":3,"title":"CVE-2026-15748 - Unauthenticated RCE exploit for WordPress Forminator plugin (≤1.56.1).
