CVE-2021-25641 is a critical deserialization vulnerability affecting Apache Dubbo versions prior to 2.7.8 and 2.6.9. An unauthenticated remote attacker can manipulate the serialization ID in the byte preamble, forcing the server to use a weak deserializer like Kryo or FST if present in the classpath. This allows for arbitrary code execution, leading to a complete compromise of confidentiality, integrity, and availability. While no public exploits, Metasploit modules, or Nuclei templates are currently available, and community discussion is minimal, the vulnerability's high CVSS score and EPSS percentile indicate a significant risk.
