Was a pain but I build them myself and it work perfect, no more vulnerability warning in Meta Quest Portal.
I going to shared here LibVorbisUpdateForUnreal 4 - Google Drive
One rar is for the Dlls in Engine/Binaries/Thirdparty/ (OGG and Vorbis)
The other rar for the libs in Engine/Source/Thirdparty/ (OGG and Vorbis)
Overwrite both folders.
It should work for both Unreal 4 and Unreal 5.
Enjoy.
