This is due to the `PMCS::action_handler()` method processing the `$_GET['delete']` parameter without any sanitization, authorization check, or nonce verification. The unsanitized filename is concatenated with the storage directory path and passed to `unlink()`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server by using `../` path traversal sequences, including `wp-config.php` which would force WordPress into the installation wizard and allow full site takeover."},{"lang":"es","value":"El plugin Perfmatters para WordPress es vulnerable a la eliminación arbitraria de archivos a través de salto de ruta en todas las versiones hasta la 2.5.9.1, inclusive. Esto se debe a que el método 'PMCS::action_handler()' procesa el parámetro '$_GET['delete']' sin ninguna sanitización, verificación de autorización o verificación de nonce. El nombre de archivo no sanitizado se concatena con la ruta del directorio de almacenamiento y se pasa a 'unlink()'. Esto hace posible que atacantes autenticados, con acceso de nivel Suscriptor y superior, eliminen archivos arbitrarios en el servidor utilizando secuencias de salto de ruta ' ../ ', incluyendo 'wp-config.php', lo que forzaría a WordPress al asistente de instalación y permitiría una toma de control completa del sitio."}],"affected":[{"source":"security@wordfence.com","affectedData":[{"vendor":"perfmatters","product":"Perfmatters","defaultStatus":"unaffected","versions":[{"version":"0","lessThanOrEqual":"2.5.9.1","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","baseScore":8.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-03T12:48:51.557866Z","id":"CVE-2026-4350","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@wordfence.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"}]}],"references":[{"url":"https://perfmatters.io/docs/changelog/","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/58b9dab8-8539-4b53-b08d-f6ee3e1e744c?source=cve","source":"security@wordfence.com"}]}}]}
