CVE-2020-9480 is a critical authentication bypass vulnerability affecting Apache Spark 2.4.5 and earlier, specifically when configured with a standalone resource manager. An unauthenticated attacker can exploit a specially-crafted RPC to the master, bypassing the shared secret authentication, to launch applications and execute arbitrary shell commands on the host machine. This vulnerability carries a CVSS score of 9.8 (CRITICAL) due to its network-based attack vector, low complexity, and high impact on confidentiality, integrity, and availability. While not currently listed in CISA's KEV catalog or showing active exploitation, a Nuclei template exists for detection, and its high EPSS score (0.93177) indicates a significant likelihood of future exploitation.
