    Inefficient Algorithmic Complexity

    Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the XmlFrameDecoder process. An attacker can cause the server's EventLoop thread to exhaust CPU resources and become unresponsive by sending a specially crafted XML payload, such as repeated </ characters, which forces the decoder to repeatedly rescan the entire buffer.

    How to fix Inefficient Algorithmic Complexity?

    Upgrade io.netty:netty-codec-xml to version 4.1.136.Final, 4.2.16.Final or higher.

    XML External Entity (XXE) Injection

    Affected versions of this package are vulnerable to XML External Entity (XXE) Injection in the XmlDecoder file when XML input containing a DOCTYPE declaration is processed by an AsyncXMLInputFactory without security configuration, leaving DTD and entity handling enabled. An attacker can access sensitive files or internal network resources by delivering crafted XML data to the channel pipeline.

    How to fix XML External Entity (XXE) Injection?

    Upgrade io.netty:netty-codec-xml to version 4.1.136.Final, 4.2.16.Final or higher.
