CVE-2021-23352

CVE-2021-23352 is a critical vulnerability affecting the madge package prior to version 4.0.1, allowing arbitrary command execution. An attacker can exploit this by manipulating the graphVizPath option, which is then executed by childprocess.exec when image(), svg(), or dot() functions are called. With a CVSS score of 9.8 (Critical), this vulnerability has a network-based attack vector, low attack complexity, and results in complete compromise of confidentiality, integrity, and availability. While there is no evidence of active exploitation, public exploit code, or significant community discussion, its high severity warrants immediate patching.
