**Name of the Vulnerable Software and Affected Versions** Microsoft Exchange Server (affected versions not specified) **Description** Microsoft Exchange Server contains a server-side request forgery (SSRF) issue, which occurs when a server fails to properly validate requests. This allows an authorized attacker to perform spoofing over a network. Additionally, incorrect input neutralization during the generation of web pages may lead to cross-site scripting (XSS), a technique where malicious scripts are injected into trusted websites, further enabling identity spoofing. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Microsoft Exchange Server 2016 CU23 Microsoft Exchange Server 2019 CU14 Microsoft Exchange Server 2019 CU15 Microsoft Exchange Server SE **Description** Microsoft Exchange Server contains a Server-Side Request Forgery (SSRF) flaw, which occurs when a server fails to properly validate requests. This allows an authorized mailbox user to force the server to make HTTP requests to internal networks, enabling internal network reconnaissance and the disclosure of sensitive information from internal HTTP services. The issue stems from the fact that intranet address validation is gated on the `isBposUser` variable, which is always `false` for on-premises installations, causing them to skip the security check entirely. Exploitation is achieved via a SOAP request to the EWS InstallApp endpoint using a crafted `ManifestUrl` parameter. **Recommendations** Update Microsoft Exchange Server 2016 CU23 to the June 2026 SU. Update Microsoft Exchange Server 2019 CU14 to the June 2026 SU. Update Microsoft Exchange Server 2019 CU15 to the June 2026 SU. Update Microsoft Exchange Server SE to the June 2026 SU.

**Name of the Vulnerable Software and Affected Versions** Microsoft Exchange Server (affected versions not specified) **Description** Improper neutralization of input during web page generation leads to cross-site scripting (XSS), a condition where malicious scripts are injected into trusted websites. This allows an unauthorized remote attacker to perform spoofing attacks over a network. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Windows Telephony Service (affected versions not specified) **Description** A use after free issue in the Windows Telephony Service allows an authorized attacker to elevate privileges locally. Use after free is a memory corruption flaw that occurs when an application continues to use a pointer after it has been freed. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Windows Kernel (affected versions not specified) **Description** A stack-based buffer overflow in the Windows Kernel allows an authorized attacker to elevate privileges locally. A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially overwriting adjacent memory. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Windows USB Print Driver versions prior to April 2026 **Description** A heap-based buffer overflow in the Windows USB Printing Stack `usbprint.sys` allows an unauthorized attacker to elevate privileges. This issue can be exploited through a physical attack. **Recommendations** Update to the version released in April 2026.
