Answer in brief
CVE-2026-55404 records a High severity (CVSS 7.5) vulnerability in yt-dlp: Downstream command injection via improper sanitization of yt-dlp --write-link output. The current sources do not mark it as known exploited. The current feed maps yt-dlp/yt-dlp (generic). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

yt-dlp and youtube-dl are command-line audio/video downloaders. Prior to 2026.7.4, the --write-link, --write-url-link, and --write-desktop-link options can write .url or .desktop shortcut files using attacker-controlled webpage_url or filename metadata without sufficient validation or escaping, allowing malicious file:// URI injection on Windows or newline-based desktop entry key injection on Linux that can execute commands if the generated shortcut is opened. This issue is fixed in version 2026.7.4.
