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."}],"title":"Cost Calculator Builder PRO <= 4.0.3 - Unauthenticated Remote Code Execution via 'orderDetails' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4c8f2872-06ff-41a2-b601-77a47470de0c?source=cve"},{"url":"https://stylemixthemes.com/cost-calculator-plugin/"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-94 Improper Control of Generation of Code ('Code Injection')","cweId":"CWE-94","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":"Nox Axter"}],"timeline":[{"time":"2026-07-14T14:56:06.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-07-28T20:41:34.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-29T13:42:03.983521Z","id":"CVE-2026-14900","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":"2026-07-29T13:42:11.473Z"}}]}}
