CVE-2025-60731Network attack vector

Authenticated dangerous file upload through theme installation

Published Oct 24, 2025 · Updated Oct 24, 2025

Unrestricted file upload in PerfreeBlog 4.0.11 allows remote authenticated users to place dangerous files through theme installation. The installTheme function accepts a submitted theme archive without adequately restricting dangerous file types, but the surviving advisory does not disclose the exact validation failure or storage path. A low-privileged account is required, and the public record does not confirm execution of an uploaded file or disclose where it becomes reachable.
