Echo: protobufjs: security update to 7.5.6

medium Tenable Cloud Security Plugin ID 464042

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 generated message constructors copied enumerable properties from a provided properties object
 without filtering the __proto__ key. If an application constructed a message from an attacker-controlled
 plain object, an own enumerable __proto__ property could alter the prototype of that individual message
 instance. This vulnerability is fixed in 7.5.6 and 8.0.2. (CVE-2026-44292)

Solution

Update the protobufjs library and its related packages to version 7.5.6 or later.
