CVE Severity Published▾ Status Exploitation Description
CVE-2026-59171 Medium 2026-11-06 No exploit published Proof of concept only JSON-java is a reference implementation of a JSON package in Java. From version 20150729 through 20260522, JSONTokener.nextSimpleValue can accumulate unbounded numeric tokens before JSONObject.stringToNumber passes them to BigInteger or BigDecimal conversion without a length limit. An application that parses attacker-controlled JSON or XML through JSONObject, JSONArray, or XML.toJSONObject can spend super-linear CPU time converting a sufficiently long numeric literal, blocking request-handling threads and causing denial of service. Strict mode and keep-strings settings in JSONParserConfiguration do not prevent the affected conversion path. Version 20260719 limits numeric conversion length.
CVE-2025-3588 Medium 2025-04-14 No exploit published Proof of concept only A vulnerability, which was classified as problematic, has been found in joelittlejohn jsonschema2pojo 1.2.2. This issue affects the function apply of the file org/jsonschema2pojo/rules/SchemaRule.java of the component JSON File Handler. The manipulation leads to stack-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
