CVE-2026-97380
Description
A flaw was found in MariaDB. An authenticated attacker with low privileges can achieve privilege escalation by modifying the password of another database account. This vulnerability occurs because the database server checks incorrect authorization privileges when processing a GRANT PROXY statement containing an empty password clause, allowing the attacker to compromise target accounts.
Statement
This vulnerability is evaluated as having an Important impact for Red Hat environments because an authenticated user with minimal access can escalate privileges to take over arbitrary database accounts, including administrative users, leading to a complete compromise of database confidentiality and integrity. In typical deployments across Red Hat Enterprise Linux, MariaDB hosts multi-tenant or shared application workloads where untrusted or lower-tier users might hold valid login credentials. Although exploitation requires active network access and valid database authentication, the authorization flaw permits bypassing privilege boundaries without requiring grant permissions.
Mitigation
Upgrade to the fixed version of MariaDB Server
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).
