CVE-2026-40091

Description

A flaw was found in SpiceDB. When SpiceDB starts with log level info, the startup configuration log will expose the full datastore Data Source Name (DSN), including the plaintext password. This vulnerability allows an attacker with access to these logs to obtain sensitive database credentials, potentially leading to unauthorized access to the datastore.

Statement

To exploit this vulnerability, a local attacker needs to have read access to the startup configuration log. Due to this reason, this flaw has been rated with a moderate severity.

Mitigation

To mitigate this flaw, configure the log level to 'warn' or 'error', instead of 'info'.

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.

CWE-532

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.
