Machine-written summary

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

The pyLoad-ng package, versions before 0.5.0b3.dev100, is vulnerable to server-side request forgery through the parse_urls API. An authenticated user with ADD permission can supply a URL that redirects to an internal or private IP address, bypassing the initial hostname check, which could expose cloud metadata, internal services, or localhost services. Upgrade to 0.5.0b3.dev100 or later.
