CVE-2024-49653Network attack vector

Authenticated web-shell upload via unrestricted file types

Published Oct 23, 2024 · Updated May 12, 2026

Arbitrary file upload in James Eggers Portfolleo 1.2 and earlier allows remote authenticated users to place web shells on the server. The plugin's upload handling accepts attacker-supplied files without restricting dangerous file types, allowing executable server-side content to be stored. Subscriber-level access is required; executing an uploaded web shell grants code execution in the web server's security context.
