This issue affects Apache Log4j API versions 2.13.1 through 2.25.4 and version 2.26.0. The fix for CVE-2026-34481 did not cover all code paths: when a MapMessage contains a non-finite IEEE 754 value (NaN, Infinity, or -Infinity), MapMessage.asJson() emits the corresponding bare token. RFC 8259 does not permit these tokens, so a conformant parser rejects the resulting document. The defect is reachable only when both of the following conditions hold: * The application uses the message resolver https://logging.apache.org/log4j/2.x/manual/json-template-layout.html#event-template-resolver-message of JsonTemplateLayout or any other layout that relies on MapMessage.asJson() or MapMessage.getFormattedMessage(new String[]{"JSON"}). * The application logs a MapMessage that contains an attacker-controlled floating-point value. An attacker who can supply a non-finite value can cause the affected layout to emit malformed JSON, which may corrupt the enclosing log record or disrupt downstream log ingestion and parsing. Users are advised to upgrade to Apache Log4j API 2.25.5 or 2.26.1, both of which emit RFC 8259-compliant JSON for non-finite values. #### Severity - CVSS Score: 6.3 / 10 (Medium) - Vector String: `CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N` #### References - [https://nvd.nist.gov/vuln/detail/CVE-2026-49844](https://nvd.nist.gov/vuln/detail/CVE-2026-49844) - [https://github.com/apache/logging-log4j2/pull/4163](https://redirect.github.com/apache/logging-log4j2/pull/4163) - [https://logging.apache.org/cyclonedx/vdr.xml](https://logging.apache.org/cyclonedx/vdr.xml) - [https://logging.apache.org/log4j/2.x/manual/json-template-layout.html#event-template-resolver-message](https://logging.apache.org/log4j/2.x/manual/json-template-layout.html#event-template-resolver-message) - [https://logging.apache.org/security.html#CVE-2026-49844](https://logging.apache.org/security.html#CVE-2026-49844) - [https://github.com/apache/logging-log4j2/commit/19edb23e162d6c728a8c2221a240037d389ed300](https://redirect.github.com/apache/logging-log4j2/commit/19edb23e162d6c728a8c2221a240037d389ed300) - [https://github.com/apache/logging-log4j2/commit/feadf8eb0b4acb6ddfa4c0ab2bbc6d88b8e12d82](https://redirect.github.com/apache/logging-log4j2/commit/feadf8eb0b4acb6ddfa4c0ab2bbc6d88b8e12d82) - [https://github.com/apache/logging-log4j2/releases/tag/rel/2.25.5](https://redirect.github.com/apache/logging-log4j2/releases/tag/rel/2.25.5) - [https://github.com/apache/logging-log4j2/releases/tag/rel/2.26.1](https://redirect.github.com/apache/logging-log4j2/releases/tag/rel/2.26.1) - [https://github.com/advisories/GHSA-qv9r-c865-cp47](https://redirect.github.com/advisories/GHSA-qv9r-c865-cp47) This data is provided by the [GitHub Advisory Database](https://redirect.github.com/advisories/GHSA-qv9r-c865-cp47) ([CC-BY 4.0](https://redirect.github.com/github/advisory-database/blob/main/LICENSE.md)). </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
