Neo4j < 5.26.21 Information Disclosure Vulnerability (CVE-2026-1622)

medium Nessus Plugin ID 298972

Language:

Synopsis

The remote web server is affected by a Information Disclosure vulnerability

Description

According to its self-reported version number, the version of Neo4j running on the remote host is a version prior to 5.26.21. It is, therefore, affected by a information disclosure vulnerability where The obfuscate_literals option in the query logs does not redact error information, exposing unredacted data in the query log when a customer writes a query that fails. It can allow a user with legitimate access to the local log files to obtain information they are not authorised to see.
 Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number

Solution

Upgrade to Neo4j version 5.26.21 or later.
