Server-side request forgery (ssrf) in Power Automate allows an authorized attacker to elevate privileges over a network.
AnalysisAI
Privilege elevation in Microsoft Power Automate (Power Platform cloud service) lets an authenticated, low-privileged attacker abuse a server-side request forgery flaw (CWE-918) to make the service issue requests to internal/backend endpoints, resulting in a scope-changing escalation with total confidentiality, integrity, and availability impact. The CVSS 3.1 base score is 9.9 with a changed scope, reflecting that the SSRF crosses a trust boundary into resources beyond the vulnerable component. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated, authorized foothold in Microsoft Power Automate / Power Platform (CVSS PR:L - 'an authorized attacker'), meaning the actor must already hold a valid low-privilege account or tenant context; it is network-reachable (AV:N), needs no user interaction (UI:N), and is low-complexity (AC:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed: the CVSS 3.1 base score is a near-maximal 9.9 (AV:N, AC:L, PR:L, UI:N, S:C, C:H/I:H/A:H) driven by network reach, low complexity, minimal privilege, and total technical impact across a changed scope, yet the exploitation-likelihood signals are muted - EPSS is only 0.33% (26th percentile), there is no KEV listing, and CISA's SSVC decision records Exploitation: none and Automatable: no while still rating Technical Impact as total. … 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 | Because Power Automate is a Microsoft-operated cloud service, remediation is primarily service-side and delivered by Microsoft; per the MSRC advisory (https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-65818) no customer-installable patch version is enumerated (Patch available per vendor advisory / service-side fix), so verify the MSRC guidance for your tenant and confirm the fix is deployed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit all Power Automate users and restrict low-privileged account creation; enable multi-factor authentication for all users with Power Automate access. …
