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"}}]}}
