Echo: fast-uri: security update to 2.4.5

high Tenable Self-Hosted Container Security Plugin ID 463280

Description

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

 - fast-uri is a URI parser for Node.js. During parsing it runs a legacy decoding pass over the scheme
 component and never re-escapes the result, and serialization writes the scheme back out verbatim, unlike
 the host component which is re-escaped. As a result an input whose scheme carries percent-encoded slashes
 parses as a scheme with no authority, so the parsed host and error are both undefined, yet resolving or
 normalizing that same input emits a network-path reference whose authority is attacker-chosen and re-
 parses to that host. An application that allowlists on the parsed host, or treats a reference with no
 authority as safe to resolve against its base, gets the opposite of what it checked, giving an off-site
 redirect, server-side request forgery, or address-policy bypass. The legacy decoder also expands non-
 standard escape forms, widening the issue past upstream filters, and control characters in the scheme can
 reach the output as raw carriage return and line feed. The affected versions are 2.3.1 up to but not
 including 2.4.5, 3.0.0 up to but not including 3.1.6, and 4.0.0 up to but not including 4.1.3. The issue
 is fixed in 2.4.5, 3.1.6, and 4.1.3, which reject a scheme that is not valid after decoding. Users should
 upgrade to a patched version. (CVE-2026-76172)

Solution

Update the fast-uri library and its related packages to version 2.4.5 or later.
