Use after free in Windows Credential Providers allows an authorized attacker to elevate privileges locally.
AnalysisAI
Privilege escalation via use-after-free in Windows Credential Providers allows a local, low-privileged authenticated attacker to gain full system control on Windows 11 and Windows Server 2025. The CWE-416 flaw exists in the credential provider subsystem, which handles authentication UI interactions; triggering the UAF condition (AC:H) under the right timing yields C:H/I:H/A:H impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have an existing low-privileged authenticated session on the target machine (PR:L); remote unauthenticated exploitation is not possible given AV:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 score (AV:L/AC:H/PR:L/UI:N) correctly frames this as a local privilege escalation with meaningful exploitation barriers - a low-privileged user must trigger a heap-state race or timing condition (AC:H), which demands a reliable primitive or repeated attempts. … 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 | Apply Microsoft's Patch Tuesday update addressing CVE-2026-69814 via Windows Update or WSUS. … Detailed patch versions, workarounds, and compensating controls in full report. |
