Machine-written summary

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

yt-dlp versions from 2022.10.04 before 2023.11.14 are affected. A malicious website can use the Generic extractor to set an arbitrary proxy for requests yt-dlp makes, allowing a man-in-the-middle attack that may expose cookies not marked secure. Upgrade to yt-dlp 2023.11.14 or later; as a workaround, disable the Generic extractor with --ies default,-generic.
