CVE-2026-13716Public exploitNetwork attack vectorHinoki check available

Authenticated code execution via unchecked upload paths

Published Aug 11, 2026 · Updated Aug 11, 2026

Path traversal in Crafty Controller 4.4.0 through 4.10.7 allows remote authenticated users to write files and execute code. The upload handler joins attacker-controlled fileName, fileId, and chunkId values into destination and temporary paths without resolving them or enforcing directory containment. An account with SERVER_CREATION or per-server FILES permission can escape the upload sandbox and run template code as the Crafty service account.
