Summary

An issue was discovered in PlayJava in Play Framework 2.6.0 through 2.8.2. The body parsing of HTTP requests eagerly parses a payload given a Content-Type header. A deep JSON structure sent to a valid POST endpoint (that may or may not expect JSON payloads) causes a StackOverflowError and Denial of Service.

Patch / fix

  • maven com.typesafe.play:play 2.7.6, 2.8.3
  • maven com.typesafe.play:play-java 2.7.6, 2.8.3
