Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an authorized attacker to disclose information locally.
AnalysisAI
Windows File Explorer on a wide range of Microsoft Windows client and server versions exposes sensitive information to locally authenticated standard users, achieving high confidentiality impact without requiring elevated privileges. The flaw (CWE-200) is confined to the local attack surface - CVSS AV:L/PR:L - meaning the attacker must already hold an interactive session on the target system. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a locally authenticated session with at least standard user (low) privileges on the affected Windows system - confirmed by CVSS AV:L/PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.5 (Medium) accurately reflects a constrained but genuine risk: AV:L limits exploitation to actors with existing local access, AC:L indicates no special configuration or timing is required once access is obtained, and PR:L means a standard user account suffices. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A standard domain user with an active interactive session on a shared Windows terminal server navigates within File Explorer in a way that inadvertently surfaces sensitive file metadata, paths, or content belonging to other users or privileged accounts - for example, through a shared thumbnail cache or improperly scoped shell data structure. The attacker requires no special tooling, no network position, and no elevated credentials; a normal Windows logon and File Explorer interaction suffice. … |
| Remediation | The primary remediation is to apply the vendor-released patch documented in the Microsoft Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-50456. … Detailed patch versions, workarounds, and compensating controls in full report. |
