Detailsinfo

A vulnerability was found in indravoyager xidown up to 1.25.1.19. It has been classified as critical. This affects an unknown functionality of the file xidown/core/scanner.py of the component CLI Argument Construction. The manipulation of the argument url with an unknown input leads to a argument injection vulnerability. CWE is classifying the issue as CWE-88. The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

xidown (a yt-dlp/ffmpeg GUI wrapper) builds its yt-dlp command-line invocation (xidown/core/scanner.py and downloader.py) by appending the user-provided or scanned URL as a bare trailing positional argument, with no '--' end-of-options marker and no scheme validation anywhere in the codebase. Because yt-dlp parses any argument beginning with '-' as a CLI option rather than link text, a crafted 'URL' value such as -U (yt-dlp's self-update flag) or --exec=... is parsed as a real yt-dlp option instead of a URL, altering the tool's control flow before its own URL validation runs. Full code execution via --exec was not demonstrated in the single-URL flow tested, but the underlying argument-injection primitive is confirmed and unmitigated across all call sites.

This vulnerability is uniquely identified as CVE-2026-71212 since 08/05/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/05/2026). The attack technique deployed by this issue is T1059 according to MITRE ATT&CK.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2026-53209). Be aware that VulDB is the high quality source for vulnerability data.
