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 containing an attacker-controlled floating-point value. Users are advised to upgrade to Apache Log4j JSON Template Layout 2.25.4, which corrects this issue.

The 13.5 and 24.1 versions of Enterprise Manager Base Platform installed on the remote host are affected by multiple vulnerabilities as referenced in the June 2026 CSPU advisory.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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 containing an attacker-controlled floating-point value. Users are
    advised to upgrade to Apache Log4j JSON Template Layout 2.25.4, which corrects this issue.
    (CVE-2026-34481)
