Information disclosure via unredacted query errors
Published Feb 4, 2026 · Updated Feb 4, 2026
Information disclosure in Neo4j Enterprise and Community editions allows local users to read unredacted query data from query.log. The obfuscate_literals option redacts query literals but leaves error information unchanged when a query fails, causing sensitive values to be written to the log. Affected versions are 4.4 through 4.4.47, 5.0 through 5.26.20, and 2025.01 through 2026.01.2; exploitation requires the option to be enabled and access to local log 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=2025.01 <2026.01.3
- Affected versionversion=4.4 <4.4.48
- Affected versionversion=5.0 <5.26.21
