All LineageOS builds, regardless of whether they are official or unofficial, are insecure by default as the binary blobs are outdated and will never be updated.

All LineageOS builds, regardless of whether they are official or unofficial, are insecure by default as the binary blobs are outdated and will never be updated. LineageOS is the point of last resort if you want to update your EOL device to a newer OS build while sacrificing security. >Nexus and Pixel devices are top of the line phones that are famously well supported by ROMs, the sort of "check for support in advance" I mentioned. If the bootloader can be unlocked then there is going to be a LineageOS build for it. >Unofficial builds are usually distributed without source (let alone working build instructions) as opaque blobs that you have to trust some random XDA user, with no verifiable background, didn't do anything too horrible to. At best, you're pretty much guaranteed to be getting a build without selinux enabled; at worst, you're getting straight up malware. The vast majority of Unofficial LineageOS builds are performed by Recognized XDA developers. So, no, we're not trusting some random XDA developer. Additionally, SELinux is in enforcing mode on my unofficial Android 13 Nexus 5 build.
