That's false. I've seen it repeated a few times but it
remains false. Mostly, this falsehood seems to be repeated
in tandem with efforts one could interpret as attempts
to create FUD about Internet related security.

TLS started in the IETF as a compromise between Netscape
and Microsoft proposals for how to secure HTTP.

X.509 started as part of X.400, then X.500 and is used by
TLS. Today, I would bet almost all implementers never need
to look beyond RFC5280 for X.509. And I hope it stays that
way until we somehow figure out how to retire X.509.
