PatchTheCVECVE-2026-72571: A path traversal vulnerability in mustafaakin/cast-localvideo (all versions) allows an unauthenticated remote
CVE-2026-72571 is a high-severity flaw (CVSS 7.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A path traversal vulnerability in mustafaakin/cast-localvideo (all versions) allows an unauthenticated remote attacker to read arbitrary files from the server. The app.js handler at lines 151-153 passes the user-supplied req.body.dir parameter directly to res.sendFile() without sanitization, enabling directory traversal via absolute paths or ../ sequences to read sensitive system files.
Why this priority
- High severity
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
