SCA: security update for stimulus_reflex (GHSA-f78j-4w3g-4q65)

high Tenable Self-Hosted Container Security Plugin ID 414354

Description

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

 - stimulus_reflex is a system to extend the capabilities of both Rails and Stimulus by intercepting user
 interactions and passing them to Rails over real-time websockets. In affected versions more methods than
 expected can be called on reflex instances. Being able to call some of them has security implications. To
 invoke a reflex a websocket message of the following shape is sent:
 `\"target\":\"[class_name]#[method_name]\",\"args\":[]`. The server will proceed to instantiate `reflex`
 using the provided `class_name` as long as it extends `StimulusReflex::Reflex`. It then attempts to call
 `method_name` on the instance with the provided arguments. This is problematic as `reflex.method
 method_name` can be more methods that those explicitly specified by the developer in their reflex class. A
 good example is the instance_variable_set method. This vulnerability has been patched in versions 3.4.2
 and 3.5.0.rc4. Users unable to upgrade should: see the backing GHSA advisory for mitigation advice.
