Revision History

• 2024-07-09: Information published.
• 2024-07-25: Revised the Security Updates table to include PowerShell 7.4 and 7.2 because these versions of PowerShell 7 are affected by this vulnerability. See https://github.com/PowerShell/Announcements/issues/64 for more information.
• 2024-10-08: In the Security Updates table, added .NET 6.0 as it is also affected by this vulnerability. Note that there is no security update for .NET 6.0 to address this vulnerablity. HTTP/3 support was only experimental in .NET 6.0, so if you are using .NET 6 you must update your application to .NET 8 to be protected.
