CVE-2026-47281 Jun 09, 17:17 CRITICAL PATCH Act Now

Privilege escalation in Microsoft Visual Studio Code allows remote unauthenticated attackers to elevate privileges over a network when a victim performs a required interaction, due to improper input validation classified as missing authentication (CWE-306). The flaw carries a critical CVSS 9.6 score with scope change, meaning a successful attack impacts resources beyond the vulnerable component. No public exploit identified at time of analysis, but the user-interaction trigger combined with VS Code's massive developer install base makes this a notable supply-chain-adjacent risk.

The CVSS 8.4 score reflects high impact on confidentiality, integrity, and availability without requiring privileges or user interaction, though the attack vector is local. No public exploit is identified at time of analysis and the issue is not listed in CISA KEV.

Path traversal in Microsoft SharePoint Server (2016, 2019, and Subscription Edition) enables an authenticated low-privileged attacker to execute code over a network by escaping the intended directory scope. Affected builds span all three actively maintained SharePoint Server product lines, with vendor-confirmed patches available for each. No public exploit code has been identified at time of analysis, and this CVE is not currently listed in the CISA KEV catalog; however, the low attack complexity (AC:L) and no user interaction requirement (UI:N) make it a credible target for exploitation once an attacker has any valid SharePoint credential.
