CVE-2021-21341 is a denial-of-service vulnerability affecting XStream versions prior to 1.4.16, a Java library for XML serialization, and consequently impacts products like Apache, Debian, and Oracle that utilize it. This high-severity vulnerability (CVSS 7.5) allows a remote attacker to consume 100% CPU resources by manipulating the input stream, leading to a denial of service without requiring user interaction. While no public exploits or Metasploit modules are available, and community discussion is minimal, its FAUCET Risk Score of 90/100 indicates a significant potential risk. Organizations are advised to update XStream to version 1.4.16 or implement a strict security framework whitelist to mitigate this threat.
