CVSS 3.1 Score 8.8 of 10 (high)
Details
Summary
CVE-2024-28121 affects the stimulus_reflex system, which intercepts user interactions in Rails and Stimulus applications and passes them over real-time websockets. In affected versions, more methods than intended can be called on reflex instances, potentially leading to security implications. The server instantiates reflexes based on the provided class name and attempts to call the specified method with no argument checks. This vulnerability allows unintended method calls, such as instance_variable_set, posing a risk. The issue has been resolved in versions 3.4.2 and 3.5.0.rc4. Users unable to upgrade should consult the GHSA advisory for mitigation guidance.
