{"id":"CVE-2018-14028","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-14028","generatedAt":"2026-10-28T22:20:32.880Z","title":"This allows for PHP files to be uploaded.","description":"In WordPress 4.9.7, plugins uploaded via the admin area are not verified as being ZIP files. This allows for PHP files to be uploaded. Once a PHP file is uploaded, the plugin extraction fails, but the PHP file remains in a predictable wp-content/uploads location, allowing for an attacker to then execute the file. This represents a security risk in limited scenarios where an attacker (who does have the required capabilities for plugin uploads) cannot simply place arbitrary PHP code into a valid plugin ZIP file and upload that plugin, because a machine's wp-content/plugins directory permissions were set up to block all new plugins.","published":"2018-08-10T16:29:00.000Z","lastModified":"2026-06-17T01:40:30.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":7.2,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-434"],"affected":["wordpress/wordpress"],"epss":{"score":0.15167,"percentile":0.96728,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.1257,"percentile":0.96113},{"date":"2026-09-22","score":0.15233,"percentile":0.96604}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 15.2%, higher than 97% of all known CVEs.
