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.","state":0,"publishedAt":"2026-10-28T15:19:16.649+00:00","modifiedAt":"2026-10-28T15:19:16.649+00:00","affected":[{"ecosystem":"Vendor product","name":"Ninja Forms","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"Saturday Drive\",\n                    \"product\": \"Ninja Forms\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.15.4\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:L","score":5.1,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","score":7.1,"severity":"HIGH"}],"references":["https://wordpress.org/plugins/ninja-forms/#developers","https://www.vulncheck.com/advisories/ninja-forms-wordpress-plugin-server-side-validation-bypass-via-list-fields"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-67187","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-67187","identifiers":["CVE-2026-67187"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
