babel_core needs to be upgraded in ts-jest

[jeffvc]

Github dependabot is showing a defect for @babel/helpers. ts-jest uses @babel/core, and in our code base, @babel/helpers is a transitive dependency from ts-jest, which we have upgraded to the latest version.

Any help appreciated, this is blocking us from fixing the Github reported issue.

Here is the exact wording:
When using Babel to compile regular expression named capturing groups, Babel will generate a polyfill for the .replace method that has quadratic complexity on some specific replacement pattern strings (i.e. the second argument passed to .replace).

This problem has been fixed in @babel/helpers and @babel/runtime 7.26.10 and 8.0.0-alpha.17, please upgrade. It's likely that you do not directly depend on @babel/helpers, and instead you depend on @babel/core (which itself depends on @babel/helpers). Upgrading to @babel/core 7.26.10 is not required, but it guarantees that you are on a new enough @babel/helpers version.

Hmm this is odd, ts-jest declares Babel as peer dep only

ts-jest/package.json

Line 66 in 56939f7

"@babel/core": ">=7.0.0-beta.0 <8",

I think (per https://www.npmjs.com/package/@types/babel__core) that @types/babel__core needs to be upgraded. This link shows it as 7.20.5 which is an old version. The newest one is 7.26.10. Our Devs did a hard override to fix the problem, but that is not the correct fix.
