Rambox hasn't had a stable release in a while and an increasing number
of issues which is why I don't intend to use this anymore.
While taking a closer look at the source I also realized that it uses
Electron 7.2.4[1]. This is not only EOLed[2], it also contains a few
security vulnerabilities which is why I decided to mark it as insecure.
A few (most likely not all) vulnerabilities can be found by looking at
the Electron 7 changelog[3]: after 7.2.4 there were a few more releases
with security backports - mostly from Chromium. Security issues that
were found later on (and are probably exploitable on the dependency
chain of rambox) aren't listed here. I only added two issues that seemed
applicable to `rambox`, but I haven't researched enough to check the
other ones.
