Last modified

CVE-2023-4043 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. . EPSS estimates a 0.76% chance of exploitation in the next 30 days.
