| Impact | CVSS 10.0 (Critical). Network vector, no auth, low complexity, scope change. The monitoring server typically has network access to all production databases. A single compromise can cascade to the entire infrastructure. EPSS 0.15%. |
| Exploit ScenarioDerived | An attacker scans for internet-exposed PMM Server instances, logs in via SSH with default credentials, escalates to root, and extracts stored database credentials for all monitored PostgreSQL/MySQL/MongoDB instances. |

Alert meAnalysisAIv1 – Mar 12, 2026
Percona PMM Server OVA images ship with default service account credentials that grant SSH access and sudo to root, exposing all monitoring data and managed database credentials. The scope change reflects that compromising the monitoring server gives access to all monitored infrastructure.
Earlier versions of this analysis (1)
Percona PMM Server OVA ships with default credentials enabling SSH + sudo root access, exposing all monitored database infrastructure.
RemediationAI
Upgrade to PMM2 >= 2.42.0 or PMM3 >= 3.0.0. Change all default credentials immediately. Never expose PMM Server to the internet. Rotate all monitored database credentials if exposure is suspected.
Affected ProductsAI
Percona PMM Server OVA before PMM2 2.42.0-1.ova and PMM3 3.0.0-1.ova

Technical ContextAI · show details
The OVA image includes a service account with hardcoded default credentials (CWE-1393). An attacker who discovers an exposed PMM Server can SSH in with default credentials and immediately sudo to root. Since PMM stores credentials for all monitored databases, this is a pivot point to the entire database fleet.

DescriptionCVE.org
An issue was discovered in Percona PMM Server (OVA) before 3.0.0-1.ova. The default service account credentials can lead to SSH access, use of Sudo to root, and sensitive data exposure. This is fixed in PMM2 2.42.0-1.ova, 2.43.0-1.ova, 2.43.1-1.ova, 2.43.2-1.ova, and 2.44.0-1.ova and in PMM3 3.0.0-1.ova and later.
Executive ViewAI
CVE-2025-26701 presents critical security risk rated CVSS 10.0. Successful exploitation could critically impact the confidentiality, integrity, and availability of affected systems. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.

Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
