Heap-based buffer overflow in Windows Imaging Component allows an unauthorized attacker to execute code over a network.
AnalysisAI
Heap-based buffer overflow in Windows Imaging Component (WIC) enables unauthenticated remote code execution across a broad swath of Microsoft Windows desktop and server editions from Server 2012 through Windows 11 26H1. Exploitation requires user interaction - a victim must open or process a maliciously crafted image file - after which an attacker achieves full C/I/A compromise of the targeted system. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required: a victim must open, preview, or cause a process to parse a maliciously crafted image file. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 score is well-supported by the vector: network-reachable, low complexity, no privileges required for the attacker, but user interaction (UI:R) is the distinguishing limiting factor preventing a fully drive-by CVSS 9.8 rating. … 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 the vendor-released patches via Windows Update or Microsoft Update Catalog immediately; fixed builds are version-specific (e.g., Windows 10 22H2: 10.0.19045.7725, Windows 11 24H2: 10.0.26100.9445, Windows Server 2025: 10.0.26100.33438 - full version table in the EUVD record and at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-69860). … Detailed patch versions, workarounds, and compensating controls in full report. |
