QID 983447

QID 983447: Nodejs (npm) Security Update for clang-extra (GHSA-59m2-j944-839w)

Affected versions of `clang-extra` insecurely download an executable over an unencrypted HTTP connection.

In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running `clang-extra`.

## Recommendation

No patch is currently available for this vulnerability. The package author stated that no patch is possible until llvm provides HTTPS support, and a patch would be possible if that ever happened in the future.

The best mitigation option is to reduce the risk of exploitation as much as possible. This can be done by ensuring that this package is not installed while connected to a public network. If the package is installed on a private network, the only people who can exploit this vulnerability are those who have compromised your network or those who have privileged access to your ISP, such as Nation State Actors or Rogue ISP Employees.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as Critical - 8.1 severity.
