Severity Finding Location
Low
yt-dlp dependency not version-pinned Supply Chain
The SKILL.md instructs `pip install yt-dlp` without specifying a version. This could allow a malicious package update in the future.
pip install yt-dlp
→ Use version pinning: `pip install yt-dlp==2024.03.10` or equivalent
 SKILL.md:9
Low
SSL certificate verification bypass flag present Sensitive Access
The script includes `--no-check-certificate` flag for yt-dlp, which could allow MITM attacks when using a proxy.
'--no-check-certificate'
→ Remove --no-check-certificate or make it conditional only for specific broken proxy scenarios
