CVE-2026-6057Public exploitNetwork attack vector

Unauthenticated code execution via traversed upload filename

Published Apr 10, 2026 · Updated Apr 10, 2026

Path traversal in FalkorDB Browser 1.9.3 allows remote attackers to write arbitrary files through an unauthenticated upload API. The handler replaces spaces in the multipart filename, joins it beneath public/assets, and streams the body there without rejecting traversal segments. Any network-reachable instance exposes the arbitrary-write path; immediate command execution requires development mode with Turbopack hot reload.
