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-2026-34481 Medium 2026-04-10 No exploit published No public exploit Apache Log4j's JsonTemplateLayout https://logging.apache.org/log4j/2.x/manual/json-template-layout.html , in versions up to and including 2.25.3, produces invalid JSON output when log events contain non-finite floating-point values (NaN, Infinity, or -Infinity), which are prohibited by RFC 8259. This may cause downstream log processing systems to reject or fail to index affected records. An attacker can exploit this issue only if both of the following conditions are met: * The application uses JsonTemplateLayout. * The application logs a MapMessage, or logs an object directly (e.g., via Logger.info(Object), which wraps it in an ObjectMessage), where the message contains an attacker-controlled floating-point value. Users are advised to upgrade to Apache Log4j JSON Template Layout 2.25.4, which corrects this issue. Note: The fix released in version 2.25.4 did not cover all affected code paths. CVE-2026-49844 was assigned to the remaining issue, which concerns the MapMessage.asJson() serialization in Apache Log4j API and is fixed in versions 2.25.5 and 2.26.1.
CVE-2026-24802 Medium 2026-01-27 No exploit published No public exploit Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in briandilley jsonrpc4j (src/main/java/com/googlecode/jsonrpc4j modules). This vulnerability is associated with program files NoCloseOutputStream.Java. This issue affects jsonrpc4j: through 1.6.0.
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.
CVE-2024-47855 Medium 2024-10-04 No exploit published No public exploit util/JSONTokener.java in JSON-lib before 3.1.0 mishandles an unbalanced comment string.
CVE-2023-51074 Medium 2023-12-27 No exploit published No public exploit json-path v2.8.0 was discovered to contain a stack overflow via the Criteria.parse() method.
CVE-2023-50773 Medium 2023-12-13 No exploit published No public exploit Jenkins Dingding JSON Pusher Plugin 2.0 and earlier does not mask access tokens displayed on the job configuration form, increasing the potential for attackers to observe and capture them.
CVE-2023-50772 Medium 2023-12-13 No exploit published No public exploit Jenkins Dingding JSON Pusher Plugin 2.0 and earlier stores access tokens unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.
CVE-2021-27568 Medium 2021-02-23 Protected by Waratek No public exploit An issue was discovered in netplex json-smart-v1 through 2015-10-23 and json-smart-v2 through 2.4. An exception is thrown from a function, but it is not caught, as demonstrated by NumberFormatException. When it is not caught, it may cause programs using the library to crash or expose sensitive information.
CVE-2020-13973 Medium 2020-06-09 No exploit published No public exploit OWASP json-sanitizer before 1.2.1 allows XSS. An attacker who controls a substring of the input JSON, and controls another substring adjacent to a SCRIPT element in which the output is embedded as JavaScript, may be able to confuse the HTML parser as to where the SCRIPT element ends, and cause non-script content to be interpreted as JavaScript.
