Echo: protobufjs: security update to 7.6.5

high Tenable Cloud Security Plugin ID 459586

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 7.6.5 and 8.6.6,
 protobufjs parsed option names by advancing through schema tokens until reaching an = token without
 checking for end of input, so a crafted .proto schema that opens an option declaration and ends
 prematurely can cause parse, Root.load, or Root.loadSync to loop indefinitely. This issue is fixed in
 versions 7.6.5 and 8.6.6. (CVE-2026-59877)

Solution

Update the protobufjs library and its related packages to version 7.6.5 or later.
