Hi Diana Soriano.

When you install dependencies for your projects this means you are downloading code that other developers have created and their code could have certain vulnerabilities or risks if they were not implemented properly or if you have an old version of the dependency installed.

What npm is telling you here is that it has scanned all of the dependencies that you have installed and has found that some of them have some vulnerabilities. These vulnerabilities could potentially put your website/project at risk if you decide to use these dependencies in their current state.

As Bella Bradbury pointed out, running the 'npm audit fix' command will instruct npm to try to fix these vulnerabilities automatically, however there will not always be an automatic fix, sometimes some manual intervention might be necessary and other times you will have to determine if the risk is low compared to the advantage of using that particular dependency and lastly there will be times when the project you are working on requires an old version of a dependency and therefore it cannot be updated even though it has a vulnerability.

Hopes this makes it more clear for you.
