CVE-2026-67920Public exploitNetwork attack vector

Authenticated code execution via externally controlled restore paths

Published Aug 18, 2026 · Updated Aug 20, 2026

Code injection in Halo 2.25.4 allows remote authenticated users to execute arbitrary code through the migration restore workflow. MigrationServiceImpl.restoreWorkdir() passes restoration paths to FileSystemUtils.copyRecursively(), allowing externally controlled paths to determine where content is copied. A low-privilege authenticated network session is required, and successful exploitation runs code with the Halo process privileges.
