MariaDB privilege escalation (CVE-2026-107823)

high

A high-severity MariaDB flaw lets an account that can already create users and views grant itself more privileges. Fixed releases are available on every supported branch.

MariaDB: CVE-2026-107823

  • What: CVE-2026-107823 is a privilege escalation in MariaDB Server. A database account that already holds CREATE USER plus CREATE VIEW ... WITH GRANT OPTION can give itself additional privileges.
  • Severity: High (7.2).
  • Exploited: Not known to be exploited in the wild.
  • Fixed in: 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3 and 13.0.2.
  • Mitigation: Upgrade to the fixed release for your branch. Until then, make sure application database accounts (for example, a CMS's database user) do not hold CREATE USER or CREATE VIEW WITH GRANT OPTION. Accounts without those permissions cannot use this path.

Also noted

  • Wordfence reports that attack attempts targeting PHP2Shell (CVE-2026-109618 / CVE-2026-109619) are ongoing, although it has not reported a confirmed successful compromise. Sites on older PHP builds should update.
