CVE-2025-30682: Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer).

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.83% (FIRST EPSS); higher than 57.4% of all records.
  • 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 8.0.41-1 on Azure Linux 3.0 8.0.42-1; azl3 mysql 8.0.42-1 on Azure Linux 3.0 8.0.42-1; cbl2 mysql 8.0.41-1 on CBL Mariner 2.0 8.0.42-1.

Low priority for now. Upgrade to azl3 mysql 8.0.41-1 on Azure Linux 3.0 8.0.42-1; azl3 mysql 8.0.42-1 on Azure Linux 3.0 8.0.42-1; cbl2 mysql 8.0.41-1 on CBL Mariner 2.0 8.0.42-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions that are affected are 8.0.0-8.0.41, 8.4.0-8.4.4 and 9.0.0-9.2.0. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.1 Base Score 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
