CWE-502	The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Attack-Flow Graph

Executive Summary

This vulnerability is a pre-authentication remote code execution issue in certain versions of React Server Components. It occurs because the vulnerable code unsafely deserializes payloads received from HTTP requests to Server Function endpoints, allowing an attacker to execute arbitrary code remotely without needing to authenticate.

Impact Analysis

This vulnerability can have severe impacts including full system compromise. Since it allows remote code execution without authentication, an attacker could take control of the affected server, leading to data theft, service disruption, or further attacks within the network.
