CVE-2023-4043: Excessive Iteration

November 3, 2023 (updated November 13, 2023)

In Eclipse Parsson before versions 1.1.4 and 1.0.5, 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.
