This is due to the upload_icons() function workflow moving and unzipping user-controlled ZIP files into a public uploads directory without validating extracted file types. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files (including PHP) and achieve remote code execution via the Icons icon-pack upload flow."}], "lastModified": "2026-06-17T11:00:33.590", "sourceIdentifier": "security@wordfence.com"}
