"The version of MariaDB installed on the remote host is prior to 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, 13.0.2. It
is, therefore, affected by a vulnerability as referenced in the GHSA-2m85-2x26-36rf advisory.

  - MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19,
    11.4.13, 11.8.9, 12.3.3, and 13.0.2, MariaDB's ACL cache could generate the same database-privilege cache
    key for role and localhost user names that matched because both used an empty IP component. An attacker
    with CREATE USER could create the colliding principal and, when the original principal's database
    privileges were cached, exercise privileges assigned to the other account. This issue is fixed in versions
    10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2. (CVE-2026-107822)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
