CVE-2026-62873 Aug 07, 00:16 CRITICAL NEWS HOSTED Monitor

Privilege elevation in Microsoft 365 Admin Center allows a remote, unauthenticated attacker to gain elevated permissions by exploiting improper verification of a cryptographic signature (CWE-347), consistent with the vendor-supplied 'Authentication Bypass' and 'JWT Attack' tags. The maximal 9.8 CVSS with a fully network-reachable, no-privilege, no-interaction vector makes this a critical bypass of the admin portal's trust boundary. No public exploit identified at time of analysis, and it is not currently listed in CISA KEV.

CVE-2026-56171 Jul 17, 21:34 HIGH PATCH Exploit Unlikely This Week

Information disclosure in Microsoft Remote Desktop Web Client (before 2.1.65.2) and Windows Admin Center (before 2.7.4) allows unauthenticated remote attackers to read private personal information over the network without user interaction. The CVSS 7.5 rating reflects high confidentiality impact with no integrity or availability effect. There is no public exploit identified at time of analysis, and the low EPSS score (0.55%, 42nd percentile) suggests limited near-term exploitation likelihood despite the network-reachable, unauthenticated vector.

CVE-2026-58643 Jul 16, 21:57 MEDIUM PATCH This Month

Cross-site scripting in Microsoft Windows Admin Center enables network-based spoofing attacks against users who interact with attacker-controlled content. The CVSS vector (AV:N/PR:N/UI:R/S:C) confirms that an unauthenticated remote attacker can deliver a crafted payload that executes in the victim's browser context once user interaction occurs, enabling session hijacking or administrative action spoofing within the management interface. No public exploit code or CISA KEV listing has been identified at time of analysis; a vendor patch is available via the Microsoft Security Response Center.

Remote code execution in Microsoft Windows Admin Center allows an authenticated attacker to run arbitrary code over the network by exploiting a relative path traversal (CWE-23) flaw. Any user holding valid low-privilege credentials to the WAC gateway can leverage the traversal to break out of the intended file path and achieve full compromise (confidentiality, integrity, and availability impact all High). Microsoft has published a patch via MSRC; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.

Local privilege-to-code-execution in Microsoft Windows Admin Center lets an already-authenticated, lower-privileged user abuse an improper authorization check (CWE-285) to run arbitrary code on the host where the management tool is installed. Rated CVSS 7.8 with high confidentiality, integrity, and availability impact, it requires local access and existing low-level privileges rather than remote unauthenticated reach. No public exploit identified at time of analysis, and it is not listed in CISA KEV, but Microsoft has released a fix via the MSRC update guide.

Improper authentication in Windows Admin Center (versions prior to 2.6.5.16) enables an authenticated low-privilege attacker over a network to bypass authentication controls and access sensitive information beyond their authorized scope. The flaw is classified as CWE-287 (Improper Authentication) and affects all Windows Admin Center 1809.0 installations below the patched release. No public exploit code has been identified and CISA has not listed this in KEV, indicating no confirmed active exploitation at the time of analysis.

Privilege escalation in Microsoft Windows Admin Center (versions 1809.0 before 2.6.5.16) allows an already-authenticated, low-privileged network user to gain higher privileges by exploiting a missing authorization check (CWE-862). Successful exploitation yields high integrity and availability impact with limited confidentiality disclosure. There is no public exploit identified at time of analysis, and EPSS is very low (0.05%, 16th percentile), but the CVSS base score of 8.3 and 'total' SSVC technical impact make it a meaningful risk in environments where WAC is exposed.
