CVE-2026-8795
Description
A YAML injection vulnerability exists in the Windows.Collectors.Remapping artifact of Rapid7 Velociraptor before version 0.76.6. The hostname field in client_info.json inside a collection ZIP is inserted into a YAML template via Go's text/template without escaping. An attacker providing a crafted collection ZIP can leverage literal double quotes and newlines in the hostname to break out of the YAML quoted string and inject a new mount remapping entry. When an analyst applies the generated remapping file with --remap, arbitrary VQL executes on their machine with NullACLManager (all permissions granted, unsandboxed).
