{"schema":"threatline.record/2","record":{"id":"CVE-2026-67187","aliases":[],"summary":"Ninja Forms WordPress Plugin < 3.15.4 Server-Side Validation Bypass via List Fields","details":"Ninja Forms plugin for WordPress before 3.15.4 contains an incomplete server-side validation vulnerability that allows unauthenticated attackers to submit arbitrary values to Checkbox List, Multi-Select List, Image List, Country, and State fields because NF_Abstracts_List falls through to a validate() method that only checks required-field presence. Attackers can submit crafted formula payloads through the unauthenticated nf_ajax_submit endpoint that bypass CSV escaping applied only to Textbox and Textarea fields, resulting in CSV injection when an administrator downloads and opens the exported submissions file.","categories":["Unclassified"],"product":"Ninja Forms","vendor":"Saturday Drive","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-67187","source_modified_at":"2026-10-28T15:19:16.649Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Ninja Forms","vendor":"Saturday Drive","versions":[{"status":"affected","version":"0","versionType":"semver","lessThan":"3.15.4"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-67187","source_modified_at":"2026-10-28T15:19:16.649Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Ninja Forms","ecosystem":null},"version":"3.15.4","basis":"first unaffected version stated in the CVE record"}],"cvss":5.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T15:19:16.649Z","modified_at":"2026-10-28T15:19:16.649Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-67187","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T15:19:16.649Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://wordpress.org/plugins/ninja-forms/#developers","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/ninja-forms-wordpress-plugin-server-side-validation-bypass-via-list-fields","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T15:19:16.649Z","content_hash":"74e0ca96a401f5dd30f4aa4f461742abe3587f5360bd703441dfaf0d71099e4c"}}
