Devant l’ampleur de la violation, la présidente de la CNIL a décidé de mener très rapidement des investigations afin de déterminer notamment si les mesures de sécurité mises en œuvre préalablement à l’incident et en réaction à celui-ci étaient appropriées au regard des obligations du Règlement général sur la protection des données (RGPD).

Most of the security vulnerabilities come from IEF: Insecure Exposed Functions. They are functions available to the outside that should not, such as a public dropDatabase()
for example.
Next comes Routing Abuse tied for second with memory corruption issues. Rust has strongly type strings, so these errors occur less in Rust. The example of HTTP headers is great: Rust does not parse the header name as strings. They are present or not instead.

TL;DR security vulnerabilities introduced by new Rust contributors are largely less than C++ contributors. They use the amount of commits to measure it as experience. It confirms the claim of the
Namely, while it may still be true that Rust may feel like a more difficult language to learn, in at least some ways, new contributors benefit from its adoption, with their first contributions being less than 2% as likely to introduce vulnerabilities as C++, and first-time contributors appearing at a notably higher rate in the projects examined.
The results should not be used as is, as there are some effects:

To test he new "this probably should be an f string" checker, they generated a list of the most popular python repositories on Github by using Github's topic search API [with this script].
With the rule:
GIVEN a string does not have an f prefix
WHEN the string contains {foo}
AND foo is in scope
THEN it’s probably missing an f prefix
And minimizing the false positive such as
str.format(…)
call or str.format_map(…)
`@when('{user} accesses {url}.')
A big one !

Oh boy... that's pretty scary.
To deliberately introduce security holes, sometimes minor changes are enough. For example replace "==" (comparison sign) by "=" (assignment). These "attacks" are visible to a trained eye.But what happens if the eye can't see anymore? With Unicode, it is possible to use characters that look like our Latin alphabet, but are not, or worse change the writing order (left-right) so that the text is displayed one way in the text editor, while the compiler will interpret it differently. This opens up the possibility of inserting security holes that are almost impossible to see, even if you have the source code in front of you in your text editor.
(For an example of left-right inversion, go to this page: https://sebsauvage.net/wiki/ and look for my email address in the page: It shows up normally, but if you look at the html source, it shows up as a different text).I think it would be interesting if text editors had an option to display in a particular color everything that is not purely "Latin text" (0000-024F), as well as Unicode characters that cause changes (backspace, change of direction).
Proof-of-concept of this attack in different languages can be seen here: https://github.com/nickboucher/trojan-source
(from https://sebsauvage.net/links/?QRVnDw)
We can develop an extension for each editor that highlights these characters easily !
