CVE-2026-25212
Percona Monitoring And Management ≤ 3.7.0
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-25212 is a critical-severity Execution with Unnecessary Privileges (CWE-250) vulnerability in Percona Monitoring And Management. Its CVSS base score is 9.9 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Process Injection (T1055); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-6 (Least Privilege) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-25212 is a critical vulnerability affecting Percona Monitoring and Management (PMM) versions prior to 3.7. The flaw stems from an internal database user retaining specific superuser privileges, which enables an attacker with pmm-admin rights to exploit the "Add data source" feature. This allows breakout from the database context to execute arbitrary shell commands on the underlying operating system. The issue is classified under CWE-250 (Execution with Unnecessary Privileges) and carries a CVSS v3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
An attacker requires only low-privilege pmm-admin access to exploit this vulnerability remotely over the network with no user interaction needed. Successful exploitation grants full remote code execution on the host OS, providing complete confidentiality, integrity, and availability impact due to the scope change from changed components.
Percona addressed this vulnerability in PMM 3.7.0, as detailed in the official release notes, which describe it as an authenticated remote code execution issue via internal data source. Security practitioners should upgrade to PMM 3.7.0 or later to mitigate the risk, per the advisory at https://docs.percona.com/percona-monitoring-and-management/3/release-notes/3.7.0.html#authenticated-remote-code-execution-via-internal-data-source-cve-2026-25212.

Vulnerability Data
An issue was discovered in Percona PMM before 3.7. Because an internal database user retains specific superuser privileges, an attacker with pmm-admin rights can abuse the "Add data source" feature to break out of the database context and execute shell…

Mitigating Controls (NIST 800-53 r5) AI
Least privilege directly requires that only the minimum necessary authorizations are granted, structurally eliminating execution with unnecessary privileges.

PR.AA-05 directly enforces least privilege so largely eliminates CWE-250 at design time, yet the weakness can still arise from runtime escalation paths, third-party code, or misapplied role definitions outside this single control.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
The requirement to restrict privileged access and apply segregation of duties limits the number of processes or accounts that must run with elevated rights, lowering the impact of unnecessary privilege assignments.
Requiring explicit justification and time-limited grants discourages the routine allocation of unnecessary privileges that would otherwise allow execution with more rights than required.
Forcing distinct roles for initiating versus executing changes reduces the chance that an individual will run with unnecessary privileges to perform both steps.
Independent scrutiny can identify processes or services still running with unnecessary privileges and drive their reduction before an attacker can abuse them.
Restricting privileged utilities to the fewest trusted users and requiring explicit authorization directly stops developers or operators from embedding or invoking code that runs with unnecessary elevated rights.
Mandating separate non-privileged identities for routine work and restricting privileged accounts to administrative tasks reduces the chance that everyday operations run with unnecessary elevated rights.
