Machine-written summary

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

Streamlink versions before 8.6.0 are vulnerable. HTTPSession follows HTTP redirects into file:// URLs, so a remote server can redirect a request Streamlink makes to a local file, and the file's contents are returned as the response body. An attacker needs only to control an http(s) URL that the victim's Streamlink run reaches, such as a playlist or manifest URL, and can then read local files on the victim's host. Upgrade to Streamlink 8.6.0 or later.
