Monitoring and Management: Use of Default Password
CVE-2025-26701 is a critical-severity use of default password vulnerability in Monitoring and Management from Percona, with a CVSS 3.1 base score of 10.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 2.42.0-1.ova, 2.43.0-1.ova, 2.43.1-1.ova as the first without the flaw, so updating Monitoring and Management to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Monitoring and Management to 2.42.0-1.ova or 2.43.0-1.ova or 2.43.1-1.ova or 2.43.2-1.ova, whichever matches your release line, or a later version.
- Read the advisory on percona.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Use of Default Password
The product uses default passwords for potentially critical functionality.
How developers prevent this class of flaw
- Prohibit use of default, hard-coded, or other values that do not vary for each installation of the product - especially for separate organizations.
- Ensure that product documentation clearly emphasizes the presence of default passwords and provides steps for the administrator to change them.
- Force the administrator to change the credential upon installation.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
