{"id":"CVE-2026-48484","state":"PUBLISHED","title":"pyLoad: Lack of Input Size Validation Leads to Denial of Service (DoS) and Process Termination","description":"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.
