Machine-written summary

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

pyLoad (PyPI package pyload-ng) versions up to and including 0.5.0b3.dev100 have an unbounded memory growth issue in the EventManager, where a new client is created and kept for each unique uuid sent to the getEvents API and inactive clients are never removed. An attacker who can authenticate to the pyLoad API with a session or API key can send many requests with unique uuids, causing the process to exhaust memory and potentially be killed by the operating system. No fixed version is listed.
