CVE-2026-72571 mustafaakin CVE debrief

Who should care

Administrators and users of the mustafaakin/cast-localvideo application should be aware of this vulnerability and take necessary actions to protect their systems. Operators, platform administrators, and security teams need to assess their exposure, apply patches or mitigations, and monitor for suspicious activity. Vulnerability management and security teams should prioritize patching and verify server file access controls.

Technical summary

The mustafaakin/cast-localvideo application has a path traversal vulnerability. The app.js file, specifically at lines 151-153, uses the req.body.dir parameter directly in res.sendFile() without sanitization. This allows an unauthenticated remote attacker to read arbitrary files from the server using absolute paths or ../ sequences. The vulnerability affects confidentiality and may allow attackers to read sensitive system files.

Defensive priority

Patch and verify server file access controls; monitor for suspicious file read requests.

Recommended defensive actions

• Apply patches or updates from the vendor if available
• Verify and restrict server file access controls
• Monitor for suspicious file read requests
• Perform inventory checks for affected systems
• Consider compensating controls like web application firewalls
