CVE-2026-1622
Description
A flaw was found in Neo4j. The obfuscate_literals option in the query logs fails to extend redaction to error messages. When a query triggers an error, unredacted data, potentially containing sensitive literals, are exposed in the logs. This issue allows an attacker with access to the local log files to obtain sensitive information they are not authorized to view, resulting in an information leak.
Statement
To exploit this issue, an attacker must have access to the local log files. Permission to run queries facilitates exploitation but access is essential to view exposed data. Due to this reason, this vulnerability has been rated with a moderate severity.
Mitigation
To mitigate this issue, restrict log file access at the operating system level. Ensure that access to the disk location where query.log (and other logs) are stored is strictly limited to authorized system administrators.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Logging sensitive user data, full path names, or system information often provides attackers with an additional, less-protected path to acquiring the information.
