CVE-2022-29244low · fixedCVSS 3.1

Packing does not respect root-level ignore files in workspaces

### Impact `npm pack` ignores root-level `.gitignore` & `.npmignore` file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` with workspaces, as of [v7.9.0](https://github.com/npm/cli/releases/tag/v7.9.0) & [v7.13.0](https://github.com/npm/cli/releases/tag/v7.13.0) respectively, may be affected and have published files into the npm registry they did not intend to include. ### Patch - Up

CVE-2018-7408low · fixedCVSS 3

Incorrect Permission Assignment for Critical Resource in NPM

An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.

Affected: >= 0Fixed in 5.7.1source →

CVE-2013-4116info · fixed

Local Privilege Escalation in npm

Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation. ## Recommendation Update to version 1.3.3 or later.

npm CLI exposing sensitive information through logs

Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.

npm Vulnerable to Global node_modules Binary Overwrite

Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory. This b
