CVE-2026-40071 is a medium-severity flaw (CVSS 5.4) affecting pyload. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev97, the /json/package_order, /json/link_order, and /json/abort_link WebUI JSON endpoints enforce weaker permissions than the core API methods they invoke.
