I know that this will not a short time fix but recently I upgraded to NPM version 6.x.x. I created today a new SPFx project and got the following report of security issues.

I also know that this has no impact on SPFx deployed solution and has only on the build pipe but I guess some people are not aware of this.
Install NPM 6.0 create new project or run:
npm audit
Thanks, Stefan, noted and acknowledge with the right people. Closing this one as there's really nothing precisely to be done right now as 6.0 is not yet supported. This helps though with heads-up on things to double check. Thanks for that.
Thank you @vesa. Blogged about it yesterday https://n8d.at/blog/npm-6-0-and-sharepoint-framework-security-reporting/
Will add a remark that it is not officially supported yet.
Just to clarify: this issue is not about using npm@6. It's about vulnerabilities in downstream packages used by SPFx. npm@6 makes the issues visible easily, but they are still there even if you use npm@5. Also, just because vulnerabilities are reported, it doesn't mean that they apply to how the affected packages are being used in the SPFx toolchain. Clarification on these issues might help avoid concerns from organizations using SPFx, especially when using npm@6 will become mainstream and these issues will be reported by default.
It isn't clear to me :
Are you saying that there is no security issues using these packages the way spfx does or it is unsure if there is security issues?
Thx.
The reported issues change regularly as packages are being updated new issues are being discovered so if you want to be sure that none of them affects your organization, you would have to evaluate your solution at the given point in time and lock its dependencies.
