Hi, The following vulnerabilities were published for logback. CVE-2025-11226[0]: | ACE vulnerability in conditional configuration file processing by | QOS.CH logback-core up to and including version 1.5.18 in Java | applications, allows an attacker to execute arbitrary code by | compromising an existing logback configuration file or by injecting | an environment variable before program execution. A successful | attack requires the presence of Janino library and Spring Framework | to be present on the user's class path. In addition, the attacker | must have write access to a configuration file. Alternatively, the | attacker could inject a malicious environment variable pointing to | a malicious configuration file. In both cases, the attack requires | existing privilege. CVE-2026-13006[1]: | ACE vulnerability in conditional configuration file processing by | QOS.CH logback-core up to and including version 1.5.35 in Java | applications, allows an attacker to execute arbitrary code | circumventing existing protections against CVE-2025-11226 | by compromising an existing logback configuration file or by | injecting an environment variable before program execution. A | successful attack requires the presence of Janino library to be | present on the user's class path. In addition, the attacker must | have write access to a configuration file. Alternatively, the | attacker could inject a malicious environment variable pointing to | a malicious configuration file. In both cases, the attack requires | existing privilege.
