CVE-2026-17535 PUBLISHED

Velociraptor Multiple Crashes in NTFS Parser when applied to invalid NTFS Volumes

Assigner: rapid7
Reserved: 27.07.2026 Published: 11.08.2026 Updated: 11.08.2026

Velociraptor's NTFS parsing library mishandles several out of bound and memory exhaustion bugs which may be triggered by maliciously crafted NTFS images.

Typically Velociraptor's NTFS parser is used on live NTFS filesystems, limiting the opportunity of attackers corrupting the filesystem. However, in some applications (e.g.  dead disk forensics https://docs.velociraptor.app/docs/forensic/deaddisk/ ) Velociraptor may be used on untrusted NTFS image files. 

If an attacker is able to inject maliciously corrupted NTFS Volumes they can cause a crash and a Denial of Service.
