{ "url": "http://public2.vulnerablecode.io/api/vulnerabilities/58655?format=api", "vulnerability_id": "VCID-6pf4-qvrk-kugc", "summary": "The Log4j1XmlLayout from the Apache Log4j 1-to-Log4j 2 bridge fails to escape characters forbidden by the XML 1.0 standard, producing malformed XML output. Conforming XML parsers are required to reject documents containing such characters with a fatal error, which may cause downstream log processing systems to drop or fail to index affected records. Two groups of users are affected: * Those using Log4j1XmlLayout directly in a Log4j Core 2 configuration file. * Those using the Log4j 1 configuration compatibility layer with org.apache.log4j.xml.XMLLayout specified as the layout class. Users are advised to upgrade to Apache Log4j 1-to-Log4j 2 bridge version 2.25.4, which corrects this issue. Note: The Apache Log4j 1-to-Log4j 2 bridge is deprecated and will not be present in Log4j 3. Users are encouraged to consult the Log4j 1 to Log4j 2 migration guide https://logging.apache.org/log4j/2.x/migrate-from-log4j1.html , and specifically the section on eliminating reliance on the bridge.", "aliases": [ { "alias": "CVE-2026-34479" }, { "alias": "GHSA-h383-gmxw-35v2" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/88121?format=api", "purl":
