Out-of-bounds read in Microsoft Standard XPS allows an authorized attacker to disclose information locally.
AnalysisAI
Out-of-bounds memory read in the Microsoft Standard XPS (XML Paper Specification) component affects virtually every supported Windows release - from Server 2012 through Windows 11 26H1 and Server 2025 - enabling a locally authenticated user to disclose potentially sensitive memory contents. The flaw (CWE-125) carries CVSS 5.5 with high confidentiality impact but no integrity or availability consequence; scope is unchanged and no user interaction is required beyond the attacker's own session. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a locally authenticated session on the target Windows host - specifically, the attacker must hold a standard user account (PR:L per CVSS) with the ability to open or process an XPS document. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 5.5 with AV:L/PR:L correctly characterises this as a local, authenticated-only issue, eliminating remote mass-exploitation and substantially narrowing the threat to scenarios where an adversary already holds an interactive or remote-desktop session. … 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 Microsoft-released patches via Windows Update, WSUS, or Microsoft Update Catalog, targeting the per-version fixed build numbers listed above. … Detailed patch versions, workarounds, and compensating controls in full report. |
