Affected: CleanStart: mongosh

Multiple security vulnerabilities affect the mongosh package. These issues are resolved in later releases. See references for individual vulnerability details.

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.0 and 0.31.0, Axios does not correctly handle hostname normalization when checking NO_PROXY rules. Requests to loopback addresses like localhost. (with a trailing dot) or [::1] (IPv6 literal) skip NO_PROXY matching and go through the configured proxy. This goes against what developers expect and lets attackers force requests through a proxy, even if NO_PROXY is set up to protect loopback or internal services. This issue leads to the possibility of proxy bypass and SSRF vulnerabilities allowing attackers to reach sensitive loopback or internal services despite the configured protections. This vulnerability is fixed in 1.15.0 and 0.31.0.

Affected: npm: axios

Axios does not correctly handle hostname normalization when checking `NO_PROXY` rules. Requests to loopback addresses like `localhost.` (with a trailing dot) or `[::1]` (IPv6 literal) skip `NO_PROXY` matching and go through the configured proxy.

This goes against what developers expect and lets attackers force requests through a proxy, even if `NO_PROXY` is set up to protect loopback or internal services.

According to [RFC 1034 §3.1](https://datatracker.ietf.org/doc/html/rfc1034#section-3.1) and [RFC 3986 §3.2.2](https://datatracker.ietf.org/doc/html/rfc3986#section-3.2.2), a hostname can have a trailing dot to show it is a fully qualified domain name (FQDN). At the DNS level, `localhost.` is the same as `localhost`. However, Axios does a literal string comparison instead of normalizing hostnames before checking `NO_PROXY`. This causes requests like `http://localhost.:8080/` and `http://[::1]:8080/` to be incorrectly proxied.

This issue leads to the possibility of proxy bypass and SSRF vulnerabilities allowing attackers to reach sensitive loopback or internal services despite the configured protections.
