Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attack vector is strictly local (AV:L) - network-based exploitation is not possible per the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The aggregate risk signal is low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with local access - or one who can convince a user to open a malicious attachment - delivers a specially crafted Office document designed to trigger the out-of-bounds read during parsing. When the victim opens the file, the vulnerable parsing component reads beyond a buffer boundary, and the leaked memory bytes are potentially surfaced to the attacker, either via error output, file rendering artifacts, or side-channel observation. … |
| Remediation | Apply vendor-released patches available through the Microsoft Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-45485. … Detailed patch versions, workarounds, and compensating controls in full report. |
