Relative path traversal in Power Automate allows an authorized attacker to elevate privileges locally.
Articles & Coverage 1
AnalysisAI
Local privilege escalation in Microsoft Power Automate for Desktop and Power Automate agent for virtual desktops (all versions before 2.71.115.26224) is achievable via a relative path traversal flaw (CWE-23). An authenticated local user with low privileges can exploit improperly sanitized file path construction within Power Automate's RPA engine or agent service - which operates at elevated privilege - to write to or execute from an unintended directory, achieving full local privilege escalation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires a local, authenticated Windows account with at least low-level user privileges (PR:L) on a machine where Power Automate for Desktop or Power Automate agent for virtual desktops version before 2.71.115.26224 is installed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 base score (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects a realistic but non-trivial local privilege escalation: attack vector is local, complexity is high, and a low-privileged local account is required. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade both Power Automate for Desktop and Power Automate agent for virtual desktops to version 2.71.115.26224 or later, as confirmed by EUVD-sourced version data and the MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-77897. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, use endpoint detection and vulnerability scanning tools to identify all systems running Microsoft Power Automate for Desktop or Power Automate agent versions prior to 2.71.115.26224, and document systems with external user or contractor access. …
