I would put both of those projects in the category of things I wouldn't call remarkably secure, yes.

To be remarkably secure, these projects would need to not have these kinds of defects, despite the combination of being written in languages have that have a long track record of footguns and lack of initiatives to fix them (proposal-symbol-proto, and PHP's list is too long to even start) and being themselves ecosystems with questionable track records on security in the related areas (Look at $wpdb in 2026, or overall code quality and willingness to modernize, or the entirety of the model of RSC for things that are just going to nearly guarantee you punch all kinds of holes on accident).
