| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| 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-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. |
