    Description

      If the REST endpoint consumes POST requests with JSON or XML data and data are invalid, the first unrecognized token is printed to server.log. If the first token is word of length 10MB, the whole word is printed. This is potentially dangerous and can be used to attack the server by filling the disk with logs.

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
