Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: CVE-2026-59171)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in JSONTokener.nextSimpleValue() and JSONObject.stringToNumber() when parsing oversized numeric literals from user-supplied JSON or XML input. A remote attacker can send a specially crafted request body containing an excessively long numeric value to cause a denial of service.

All three primary parsing entry points are affected: new JSONObject(String), new JSONArray(String), and XML.toJSONObject(String).
