CVE-2026-23652: Microsoft Power Pages Remote Code Execution Vulnerability

Improper neutralization of special elements used in a command ('command injection') in Microsoft Power Pages allows an unauthorized attacker to execute code over a network.

Security readout for executives and security teams

Plain-English summary

A command-injection flaw in Microsoft Power Pages could let an unauthenticated remote attacker run code. Because exploitation requires no account or user action and could compromise confidentiality, integrity, and availability, affected deployments should be treated as urgent. The supplied sources do not identify affected versions or confirm active exploitation.

Executive priority

Immediate priority. Assign ownership, establish whether Power Pages is used, and require rapid remediation confirmation. The maximum CVSS score and unauthenticated remote impact justify escalation, although the supplied evidence does not establish active exploitation or define the affected version range.

Technical view

CVE-2026-23652 is a CWE-77 command-injection vulnerability in Microsoft Power Pages. Its CVSS 3.1 vector indicates network access, low complexity, no privileges, no interaction, changed scope, and high confidentiality, integrity, and availability impact. The record references an official Microsoft advisory and patch, but the supplied bundle contains no version boundaries or technical indicators.

Likely exposure

Organizations using Microsoft Power Pages may be exposed, especially where affected functionality is network-reachable. Exact exposure cannot be determined from this bundle because affected versions, configurations, and CPEs are unspecified. Inventory and Microsoft advisory comparison are required.

Exploitation context

The scoring describes a remotely reachable, unauthenticated, low-complexity path requiring no user interaction. However, exploit maturity is recorded as unproven, the CVE is not listed as KEV in this bundle, and no cited source confirms exploitation in the wild.

Researcher notes

The available evidence establishes CWE-77 and severe impact characteristics, but provides no vulnerable parameter, component, version range, indicators, or safe reproduction details. Researchers should rely on Microsoft updates for authoritative applicability and detection guidance; absence from KEV is not proof that exploitation has never occurred.

Mitigation direction

  • Review Microsoft's CVE advisory immediately for affected-service and remediation details.
  • Apply the Microsoft-provided update or remediation wherever the advisory identifies exposure.
  • Prioritize network-accessible Power Pages deployments until remediation is confirmed.
  • Use temporary access restrictions only if supported by Microsoft guidance.

Validation and detection

  • Inventory all Microsoft Power Pages deployments and responsible owners.
  • Compare each deployment's status and configuration with Microsoft's advisory.
  • Confirm the Microsoft remediation is applied to every affected deployment.
  • Review relevant telemetry for anomalous unauthenticated requests or unexpected code execution.
  • Recheck the advisory for revised affected-version or detection information.

Improper Neutralization of Special Elements used in a Command ('Command Injection')

Improper Neutralization of Special Elements used in a Command ('Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
