CVE-2024-7384Network attack vector

Arbitrary file upload via unchecked archive extraction

Published Aug 22, 2024 · Updated Apr 8, 2026

Arbitrary file upload in AcyMailing 9.7.2 and earlier allows remote authenticated users to write dangerous files via a crafted template archive. The acym_extractArchive function extracts archive members without validating their file types, allowing executable content to be written under the site. Subscriber-level WordPress access is sufficient; code execution requires the uploaded file to reach a web-executable location and be requested.
