Echo: protobufjs: security update to 1.3.3

medium Tenable Cloud Security Plugin ID 465884

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 8.6.0 and 7.6.3,
protobufjs accepted certain schema-derived names that could collide with properties used by protobufjs
runtime helpers. The known affected names are fields named hasOwnProperty, field or oneof names such as
$type when loaded through protobufjs JSON/reflection descriptors, and service methods whose generated
helper name is rpcCall. When affected message or service types were used, protobufjs could read schema-
controlled data where it expected an own-property helper, reflected type metadata, or the base RPC helper.
This could cause deterministic exceptions or recursive calls in affected decode post-checks, verification,
object conversion, reflected JSON serialization, or protobufjs RPC helper invocation. This vulnerability
is fixed in 8.6.0 and 7.6.3. (CVE-2026-54269)

Solution

Update the protobufjs library and its related packages to version 1.3.3 or later.
