CVE-2022-44581Network attack vector

Sensitive information exposure through temporary files

Published May 17, 2024 · Updated Apr 28, 2026

Insecure storage in WPMU DEV Defender Security 3.3.2 and earlier allows remote authenticated users to access sensitive temporary files. Public sources identify temporary-file screening but do not disclose the file path, data type, or code operation that leaves the contents exposed. The CNA vector requires a low-privileged account, while Patchstack's public page labels the required privilege unauthenticated; neither source identifies the exact data exposed.
