Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.132.Final and 4.2.10.Final, Netty incorrectly parses quoted strings in HTTP/1.1 chunked transfer encoding extension values, enabling request smuggling attacks. Versions 4.1.132.Final and 4.2.10.Final fix the issue.

|---|---|---|
| netty/netty | < 4.1.132 | 4.1.132 |
| netty/netty | ≥ 4.2.0, < 4.2.10 | 4.2.10 |
