This is due to missing or incorrect nonce validation on the newsblogger_install_and_activate_plugin() function. This makes it possible for unauthenticated attackers to upload arbitrary files and achieve remote code execution via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This is due to a reverted fix of CVE-2025-1305.","published":"2026-02-19T07:17:29.000Z","lastModified":"2026-09-14T23:17:14.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-352"],"affected":[],"epss":{"score":0.00399,"percentile":0.33925,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.40%).
