GHSA-6V4J-43GG-VJ32 yt-dlp: Downstream command injection via improper sanitization of yt-dlp --write-link output

Summary If the --write-link, --write-url-link or --write-desktop-link options are used with yt-dlp, it may produce output that can lead to downstream remote code execution. An attacker can craft a malicious metadata payload to achieve arbitrary command injection in the .url and .desktop shortcut...

Python Library yt-dlp < 2026.7.4 Command Injection

The detected version of the yt-dlp Python package is prior to 2026.7.4. It is, therefore, affected by a command injection vulnerability. yt-dlp and youtube-dl are command-line audio/video downloaders.

PYSEC-2026-3430 yt-dlp: Dangerous file type creation via insufficient filename sanitization (Bypass of CVE-2024-38519)

Summary A vulnerability exists in yt-dlp that allows a remote attacker to write arbitrary OS-shortcut files such as .desktop, .url, .webloc to the user's filesystem, bypassing the remediation for CVE-2024-38519. Details The fix for CVE-2024-38519 enforced an allowlist for file extensions, in orde...

PYSEC-2026-3431 yt-dlp: File Downloader cookie leak with curl

Summary If curl is used an external downloader for yt-dlp, cookies may be leaked to an unintended host upon HTTP redirect or when the host for download fragments differs from their parent manifest's. This is the equivalent to GHSA-v8mc-9377-rwjj for the curl downloader. The vulnerable behavior is...

PYSEC-2026-3432 yt-dlp: Arbitrary Command Injection when using the `--netrc-cmd` option

Summary When yt-dlp's --netrc-cmd command-line option or netrccmd Python API parameter is used, an attacker could achieve arbitrary command injection on the user's system with a maliciously crafted URL. Impact yt-dlp maintainers assume the impact of this vulnerability to be high for anyone who us...

CVE-2026-55404

A flaw was found in yt-dlp and youtube-dl, command-line tools for downloading audio and video. This vulnerability allows an attacker to inject malicious code into shortcut files .url or .desktop when certain options, such as --write-link, are used. By manipulating the webpageurl or filename...

CVE-2026-55404 yt-dlp: Downstream command injection via improper sanitization of yt-dlp --write-link output

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 webpageurl or filename metadata without sufficient validation or escaping,...

CVE-2026-55404

YT-dlp and YouTube-dl before 2026.7.4 expose a vulnerability through --write-link, --write-url-link, and --write-desktop-link that can write .url/.desktop shortcuts using attacker-controlled metadata, enabling file:// URI or desktop entry key injection and potential command execution when opened....

CVE-2026-55404 yt-dlp: Downstream command injection via improper sanitization of yt-dlp --write-link output

PYSEC-2026-2065 yt-dlp File system modification and RCE through improper file-extension sanitization

Summary yt-dlp does not limit the extensions of downloaded files, which could lead to arbitrary filenames being created in the download folder and path traversal on Windows. Since yt-dlp also reads config from the working directory and on Windows executables will be executed from the yt-dlp...

PYSEC-2026-2066 yt-dlp: `--exec` command injection when using `%q` in yt-dlp on Windows (Bypass of CVE-2023-40581)

Summary The patch that addressed CVE-2023-40581 attempted to prevent RCE when using --exec with %q by replacing double quotes with two double quotes. However, this escaping is not sufficient, and still allows expansion of environment variables. Support for output template expansion in --exec, alo...

PYSEC-2026-2063 yt-dlp Generic Extractor MITM Vulnerability via Arbitrary Proxy Injection

Impact The Generic Extractor in yt-dlp is vulnerable to an attacker setting an arbitrary proxy for a request to an arbitrary url, allowing the attacker to MITM the request made from yt-dlp's HTTP session. This could lead to cookie exfiltration in some cases. To pass extra control data between...
