Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

pyload-ng versions before 0.5.0b3.dev101 are vulnerable. The API rpc function reads entire multipart file uploads into memory without a size limit, so a large upload can exhaust server memory and terminate the process. The source says an attacker needs to be logged in or hold an API key, which the source does not describe as a requirement beyond that. Upgrade to pyload-ng 0.5.0b3.dev101 or later. Until then, enforce a maximum upload size in the web server configuration in front of pyLoad.
