CVE-2025-53893: File Browser's Uncontrolled Memory Consumption vulnerability can enable DoS attack due to oversized file processing
(updated )
A Denial of Service (DoS) vulnerability exists in the file processing logic when reading a file on endpoint Filebrowser-Server-IP:PORT/files/{file-name} . While the server correctly handles and stores uploaded files, it attempts to load the entire content into memory during read operations without size checks or resource limits. This allows an authenticated user to upload a large file and trigger uncontrolled memory consumption on read, potentially crashing the server and making it unresponsive.
