Security Scan "Vulnerability" CVE-2023-29827

[kyle-apex]

Describe the bug

@loopback/rest triggers a critical security vulnerability due to strong-error-handler's dependency on ejs.

The vulnerability is currently disputed by ejs, but does the Loopback team have an official statement/documentation as to why this isn't a vulnerability in Loopback's usage of ejs or a plan to remove ejs entirely?

Thanks!

I don't know if this is the best approach for this but I wanted to offer some help resolving this one: https://github.com/loopbackio/strong-error-handler/pull/219

Thanks for raising the issue, @kyle-apex. Since it's disputed on the merit that it's a misuse of the API to be pssing unsanitised data, it'll be dependent on how strong-error-handler uses the API.

I'll see if I can allocate some time to look into this and ger back to you.

Thanks for the PR, @KalleV; Much appreciated! Since you've kindly submitted a PR, we can probably proceed with merging the changes (after a quick review by the maintainers) regardless of the exploitability of the vulnerability in strong-error-handler.

From this issue, we should have 2 deliverables:

1. A VEX document (CSAF 2.0) detailing the exploitability - To be published under https://github.com/loopbackio/security
2. Merging https://github.com/loopbackio/strong-error-handler/pull/219
