CVE-2024-46983 is a critical deserialization vulnerability affecting Ant Group's sofa-hessian, an internal improved version of Hessian3/4. The vulnerability allows attackers to bypass the existing blacklist protection mechanism using a JDK-only gadget chain, leading to arbitrary code execution. With a CVSS score of 9.8, it presents a severe risk due to its network-based attack vector, low attack complexity, and high potential for confidentiality, integrity, and availability compromise. There is currently no evidence of active exploitation, public exploit code, or significant community discussion, but a fix is available by upgrading to sofa-hessian version 3.5.5 or maintaining a custom blacklist.
