CVE-2026-7715Public exploitNetwork attack vector

Arbitrary file write via unconstrained backup path

Published May 4, 2026 · Updated May 4, 2026

Path traversal in the arango_backup MCP tool in MCP Server for ArangoDB 0.4.0 through 0.4.7 allows remote authenticated users to write files. The handler resolves caller-controlled outputDir, creates that directory without confining it to a backup root, and writes collection JSON files there. Exploitation requires permission to invoke the tool, readable database content, and filesystem access to the selected destination; successful calls can create or overwrite JSON files and consume disk space.
