CVE-2026-48484
pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev101, the API rpc function in api_blueprint.py handles multipart/form-data uploads by reading the whole content of the uploaded file into memory with file.read(). This occurs before the data is sent to the underlying function. Since there is no size limit set at this point, a large file upload can exhaust the server's available memory which led to process termination. Version 0.5.0b3.dev101 contains a patch.
