PYSEC-2026-4293 pyLoad: Lack of Input Size Validation Leads to Denial of Service (DoS) and Process Termination

Description: The API rpc function in apiblueprint.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 uploa...
