Excessive Iteration


Severity High
Score 7.5/10


In Eclipse Parsson versions prior to 1.0.5, and 1.1.x prior to 1.1.4, Parsing JSON from untrusted sources can lead malicious actors to exploit the fact that the built-in support for parsing numbers with large scale in Java has a number of edge cases where the input text of a number can lead to much larger processing time than one would expect. To mitigate the risk, parsson put in place a size limit for the numbers as well as their scale.
