When the Windows DLL “webauthn.dll” was missing from the Operating System, and a malicious one was placed in a folder in the user’s %PATH%, Firefox may have loaded the DLL, leading to arbitrary code execution. Note: This issue only affects the Windows operating system; other operating systems are unaffected. This vulnerability affects Firefox < 78.
