CVE-2020-1947 is a critical remote code execution (RCE) vulnerability affecting Apache ShardingSphere (incubator) versions 4.0.0-RC3 and 4.0.0. The vulnerability stems from the ShardingSphere web console's use of the SnakeYAML library, which allows unmarshalling untrusted YAML inputs to Java types, leading to RCE. With a CVSS score of 9.8 (CRITICAL) and an EPSS score indicating high exploitability, this flaw presents a significant risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Despite its severity, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
