We did a study of this a few years ago[1] and the code for the instrumentation is available on github[2], the data is dated but you can see a cross section of popular apps and how far behind they were lagging over a 3 year period on page 11 of the pdf. Re: child comment, our main concern in this research was patched vulnerabilities persisting in electron apps and how damaging that could be. Details in the paper :)

I've been working on this over the years. WIP is here: https://github.com/captn3m0/electron-survey, and it doesn't look good.

I keep getting distracted by side-quests. The last one was building an Electron Zoo, and the current one is doing accurate SBOMs for each electron version.

Isn’t the threat model for these desktop apps entirely different?

I imagine that looks pretty bad. On the other hand, Electron apps often aren't running untrusted code, which makes it quite a bit harder to exploit.

Just wanted to write the same comment!
