Summary

Microsoft Windows Media Player 6.4, Windows Media Format Runtime 7.1 through 11, and Windows Media Services 4.1, 9, and 2008 do not properly use the Service Principal Name (SPN) identifier when validating replies to authentication requests, which allows remote servers to execute arbitrary code via vectors that employ NTLM credential reflection, aka "SPN Vulnerability."

Exploit prediction

15.83% chance of exploitation in the next 30 days, higher than 96% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
