CVE-2021-39141 is a high-severity remote code execution (RCE) vulnerability affecting XStream versions prior to 1.4.18, as well as products from Debian, Fedora, NetApp, and Oracle that utilize the library. This flaw allows a remote attacker to execute arbitrary code by manipulating the processed input stream, provided the XStream security framework is not configured with a restrictive whitelist. The vulnerability has a CVSS score of 8.5 (HIGH) due to its network-based attack vector, high impact on confidentiality, integrity, and availability, despite requiring high attack complexity and low privileges. While there is no evidence of active exploitation in the wild and no Metasploit or ExploitDB modules, Nuclei templates for this RCE exist, indicating potential for exploitation. Community discussion and media coverage are minimal.
