Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-78.
Summary
Video-stitch before 2.0.0-beta.1 contains an OS command injection flaw, CWE-78. File names passed to concat(), cut() and merge() are interpolated unquoted into shell-executed ffmpeg command lines, so shell metacharacters in those names are interpreted by the shell. An unauthenticated remote attacker who can influence those file names can run commands with the privileges of the Node.js process.
