  "title": "Response data exposure from buffer under-read in Apache Tomcat",
  "summary": "Apache Tomcat 11.0.0-M25 through 11.0.26 mishandles response buffering during large non-blocking writes. A later request reusing the connection may receive data from an earlier response or fail; exploitation depends on a large non-blocking response write and a subsequent request on that connection.",
