Echo: @protobufjs/utf8, protobufjs: security update to 1.1.1

medium Tenable Self-Hosted Container Security Plugin ID 465371

Description

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

 - protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2,
 protobufjs includes a minimal UTF-8 decoder that accepted overlong UTF-8 byte sequences and decoded them
 to their canonical characters instead of replacing them. An attacker who can provide protobuf binary data
 decoded through the affected UTF-8 path may be able to bypass application-level checks that inspect raw
 bytes before protobuf string decoding. For example, bytes that do not contain certain ASCII characters
 could decode to strings containing those characters. This vulnerability is fixed in 7.5.6 and 8.0.2.
 (CVE-2026-44288)

Solution

Update the protobufjs library and its related packages to version 1.1.1 or later.
