CVE-2026-1622 (opens in a new tab)How to fix?
Upgrade org.neo4j:neo4j-configuration to version 5.26.21, 2026.01.3 or higher.
Overview
Affected versions of this package are vulnerable to Insertion of Sensitive Information into Log File via the obfuscate_literals option in query logging. An attacker can access sensitive information by reading unredacted error data in the query logs when queries fail.
Notes:
This is only exploitable if the attacker has legitimate access to the local log files and can execute queries that trigger errors.
If your configuration had db.logs.query.obfuscate_literals enabled, and you wish the obfuscation to cover the error messages as well, you need to enable the new configuration setting db.logs.query.obfuscate_errors once you have upgraded Neo4j.
