CVE-2026-22015· NVD / CVE Program· CNA oracle

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Information Schema).

Noroxi assessment

Priority: Monitor (action score 17/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.24% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: azl3 mysql 8.0.45-2 on Azure Linux 3.0 8.0.46-1; cbl2 mysql 8.0.45-3 on CBL Mariner 2.0 8.0.46-1.

Low priority for now. Upgrade to azl3 mysql 8.0.45-2 on Azure Linux 3.0 8.0.46-1; cbl2 mysql 8.0.45-3 on CBL Mariner 2.0 8.0.46-1 or later.
