CVE-2026-50525 [HIGH] CWE-770 dotnet: .NET: Denial of Service due to uncontrolled resource allocation
dotnet: .NET: Denial of Service due to uncontrolled resource allocation
Allocation of resources without limits or throttling in .NET allows an unauthorized attacker to deny service over a network.
A flaw was found in .NET where uncontrolled allocation of resources can lead to a Denial of Service (DoS). An unauthorized remote attacker could exploit this vulnerability by continuously requesting resources without limits or throttling, causing the affected system to become unresponsive or crash. This can disrupt the availability of services running on the .NET framework.

Microsoft Security Advisory CVE-2026-50525 – .NET Denial of Service Vulnerability
## Executive summary
Microsoft is releasing this security advisory to provide information about a vulnerability in .NET XML Encryption (System.Security.Cryptography.Xml). This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.
A denial of service vulnerability exists in the XML encryption implementation (EncryptedXml) in .NET 8, .NET 9, and .NET 10. An attacker could exploit this vulnerability by supplying crafted encrypted XML that causes uncontrolled resource consumption, resulting in denial of service.

CVE-2026-58617 [CRITICAL] Patch Tuesday - July 2026
Microsoft is publishing 622 vulnerabilities on July 2026 Patch Tuesday , including a record-breaking 416 Windows vulnerabilities. Microsoft is aware of exploitation in the wild for two of the vulnerabilities published today, both of which are listed on CISA KEV, as well as public disclosure for one other. As usual, browser vulns are not included in the Patch Tuesday count above. Rapid7 noted last month that Microsoft no longer enumerates Chromium CVEs in the Security Update Guide. However, Microsoft has now taken the pursuit of minimalism much further, since today’s Security Update Guide no longer lists out even Microsoft vulnerabilities! Instead, we now receive a summary table of vulnerability counts by product family, as well as a new slimline “Notable CVEs” section. All of this only ser

This patch Tuesday includes a staggering 622 vulnerabilities, not including another 427 vulnerabilities in Chromium, affecting Microsoft's Edge browser. 62 of the vulnerabilities are rated critical. One was disclosed before today, and two have already been exploited.
Given the large number of vulnerabilities, it is difficult to point out "noteworthy" issues.
Already exploited vulnerabilities:
CVE-2026-56155 : Active Directory Federation Services Elevation of Privilege Vulnerability. This is an important (not critical) vulnerablity.
