Arbitrary file creation via noncanonical export paths
Published Jan 14, 2023 · Updated Mar 10, 2025
Path traversal in APOC Extended before 4.3.0.12, 4.4.0.0 through 4.4.0.11, and 5.3.0 allows attackers to create files outside exports. FileUtils.getPath accepted an unnormalized URI, while pathStartsWithOther used lexical normalization for nonexistent destinations instead of canonicalizing the file before checking the export base path. Exploitation requires an allowlisted export procedure, enabled local file export, and authenticated Cypher access or a separate Cypher injection; created files cannot overwrite existing files.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=< 4.3.0.12
- Affected versionversion=>= 4.4.0.0, < 4.4.0.12
