CVE-2021-43947 is a Remote Code Execution (RCE) vulnerability affecting Atlassian Jira Server and Data Center versions before 8.13.15 and between 8.14.0 and 8.20.3. This flaw allows remote attackers with administrator privileges to execute arbitrary code through the Email Templates feature, bypassing a previous fix. The vulnerability has a CVSS score of 7.2 (HIGH), indicating a high severity due to its network attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While no public exploit code (Metasploit, Nuclei, ExploitDB) is currently available and there is no evidence of active exploitation, its high severity warrants attention for affected organizations.
