{"id":"CVE-2026-14900","state":"PUBLISHED","title":"Cost Calculator Builder PRO <= 4.0.3 - Unauthenticated Remote Code Execution via 'orderDetails' Parameter","description":"The Cost Calculator Builder PRO plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.0.3 via the js_to_php function. This is due to insufficient sanitization of the orderDetails[*].originalValue field, which is injected verbatim into a calculator formula string passed to PHP eval() inside js_to_php(), with the regex allow-list in evaluateFormula() only filtering alphanumeric tokens and leaving non-word punctuation characters intact. This makes it possible for unauthenticated attackers to execute code on the server. The only authentication barrier is a nonce check, but the required nonce is publicly emitted on every front-end page via the wp_head hook, making it freely obtainable by unauthenticated visitors. Payloads must be non-word XOR gadgets to bypass sanitization.","publishedAt":"2026-07-29T09:31:13.766Z","updatedAt":"2026-07-29T13:42:11.473Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["StylemixThemes Cost Calculator Builder PRO"],"affected":[{"vendor":"StylemixThemes","product":"Cost Calculator Builder PRO","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.0.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/4c8f2872-06ff-41a2-b601-77a47470de0c?source=cve","https://stylemixthemes.com/cost-calculator-plugin/"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/14xxx/CVE-2026-14900.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-14900","state":"PUBLISHED","datePublished":"2026-07-29T09:31:13.766Z","dateUpdated":"2026-07-29T13:42:11.473Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-06T19:54:26.333Z"},"containers":{"cna":{"title":"Cost Calculator Builder PRO <= 4.0.3 - Unauthenticated Remote Code Execution via 'orderDetails' Parameter","descriptions":[{"lang":"en","value":"The Cost Calculator Builder PRO plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.0.3 via the js_to_php function.
