      <title>CVE-2026-1622 — Unredacted data exposure in query.log</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-1622</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; neo4j Enterprise Edition, neo4j Community Edition&lt;/p&gt;
&lt;p&gt;Neo4j Enterprise and Community editions versions prior to 2026.01.3 and 5.26.21 are vulnerable to a potential information disclosure by a user who has ability to access the local log files.&lt;/p&gt;
&lt;p&gt;The &amp;#34;obfuscate_literals&amp;#34; 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. If this user is also in a position to run queries and trigger errors, this vulnerability can potentially help them to infer information they are not authorised to see through their intended database access.&lt;/p&gt;
&lt;p&gt;We recommend upgrading to versions 2026.01.3 (or 5.26.21) where the issue is fixed, and reviewing query log files permissions to ensure restricted access. 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.&lt;/p&gt;</description>
