SCA: security update for fast-uri (GHSA-7p8r-x3mc-p8w7)

high Tenable Self-Hosted Container Security Plugin ID 445608

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - fast-uri before 4.1.2, 3.1.5, and 2.4.4 requires a literal double forward slash to recognize a URI
 authority, so a reference that uses a backslash based introducer in place of it (backslash backslash,
 forward slash backslash, or backslash forward slash) is parsed with no authority and folds into the path.
 Node's native WHATWG URL parser instead treats a backslash as interchangeable with a forward slash for
 special schemes, so the two parsers extract different hosts from the same input. Applications that use
 fast-uri to enforce host based policy such as allowlists, SSRF filtering, or redirect validation before
 passing the same URL into Node's URL or fetch consumers can be steered to an unintended host. Upgrade to
 fast-uri 4.1.2, 3.1.5, or 2.4.4. (CVE-2026-18446)

Solution

Update the fast-uri library and its related packages to version 2.4.4 or later.
