Rank Math states that the affected plugin files contained malware that could compromise a website if the plugin was activated and directs sites that activated an affected package to treat the website as compromised. The malware may establish persistent access, communicate with rank1cdn[.]com, recreate hidden backdoors on page visits, and expose WordPress credentials, database credentials, API keys, and other secrets accessible to the web server. Rank Math identifies three malicious wp_options keys, hidden PHP backdoors, unauthorized administrator accounts, a fake WordPress core file, PHP-executable .cache files, and a system cron marker as incident indicators. Only packages obtained during the vendor-confirmed window are claimed as affected; version 3.0.123 alone is not sufficient to establish compromise. Rank Math removed the affected files and released version 3.0.124 as the clean replacement."}],"affected":[{"source":"security@wordfence.com","affectedData":[{"vendor":"RankMath","product":"Rank Math SEO PRO","defaultStatus":"unaffected","versions":[{"version":"3.0.123","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Secondary","cvssData":{"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","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-20T14:10:17.459613Z","id":"CVE-2026-111862","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@wordfence.com","type":"Secondary","description":[{"lang":"en","value":"CWE-506"}]}],"references":[{"url":"https://rankmath.com/changelog/","source":"security@wordfence.com"},{"url":"https://rankmath.com/kb/pro-3-0-123-security-incident/","source":"security@wordfence.com"},{"url":"https://rdap.verisign.com/com/v1/domain/rank1cdn.com","source":"security@wordfence.com"},{"url":"https://urlscan.io/result/01a145c2-8dc8-72ff-a65d-21209ca29c4f/","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/81cd7a2c-ad0c-4dbc-b5dc-07ec866d5c1f?source=cve","source":"security@wordfence.com"}]}}]}
