CVE-2024-28121 is a critical vulnerability affecting the stimulus_reflex library, which extends Rails and Stimulus capabilities via websockets. The flaw allows attackers to call unintended methods on reflex instances, including sensitive ones like instance_variable_set, by manipulating websocket messages. With a CVSS score of 8.8 (High), this vulnerability is easily exploitable over the network with low complexity and no user interaction, potentially leading to full compromise of confidentiality, integrity, and availability. While there is no evidence of active exploitation, public exploit code, or significant community discussion, immediate patching to versions 3.4.2 or 3.5.0.rc4 is strongly recommended.
