It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-540 advisory.

  - libuv is a multi-platform support library with a focus on asynchronous I/O. The `uv_getaddrinfo` function     in `src/unix/getaddrinfo.c` (and its windows counterpart `src/win/getaddrinfo.c`), truncates hostnames to     256 characters before calling `getaddrinfo`. This behavior can be exploited to create addresses like     `0x00007f000001`, which are considered valid by `getaddrinfo` and could allow an attacker to craft     payloads that resolve to unintended IP addresses, bypassing developer checks. The vulnerability arises due     to how the `hostname_ascii` variable (with a length of 256 bytes) is handled in `uv_getaddrinfo` and     subsequently in `uv__idna_toascii`. When the hostname exceeds 256 characters, it gets truncated without a     terminating null byte. As a result attackers may be able to access internal APIs or for websites (similar     to MySpace) that allows users to have `username.example.com` pages. Internal services that crawl or cache     these user pages can be exposed to SSRF attacks if a malicious user chooses a long vulnerable username.
    This issue has been addressed in release version 1.48.0. Users are advised to upgrade. There are no known     workarounds for this vulnerability. (CVE-2024-24806)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
