Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

An elevation of privilege vulnerability exists in the Windows AppX Deployment Service (AppXSVC) due to improper handling of hard links. The flaw, tracked as CVE-2019-1130 and distinct from CVE-2019-1129, carries a CVSS 3.1 base score of 7.8 and is associated with CWE-59. It affects the AppX deployment component on supported Windows platforms.

A local attacker with low privileges can exploit the issue without user interaction to obtain full elevation of privilege, resulting in high impact to confidentiality, integrity, and availability on the affected system. The attack vector is local and requires only standard user rights to trigger the hard-link mishandling within AppXSVC.

Microsoft has published security guidance for CVE-2019-1130 through its Security Response Center, and the vulnerability appears in CISA's catalog of known exploited vulnerabilities, confirming observed in-the-wild use.
