Detailsinfo

A vulnerability, which was classified as problematic, was found in Connect2id Nimbus JOSE+JWT up to 10.0.1. Affected is some unknown processing of the component JSON Object Handler. The manipulation with an unknown input leads to a recursion vulnerability. CWE is classifying the issue as CWE-674. The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. This is going to have an impact on availability. CVE summarizes:

Connect2id Nimbus JOSE + JWT before 10.0.2 allows a remote attacker to cause a denial of service via a deeply nested JSON object supplied in a JWT claim set, because of uncontrolled recursion. NOTE: this is independent of the Gson 2.11.0 issue because the Connect2id product could have checked the JSON object nesting depth, regardless of what limits (if any) were imposed by Gson.
