CVE-2026-13006 (GCVE-0-2026-13006)
Vulnerability from nvd – Published: 2026-06-24 05:41 – Updated: 2026-07-01 11:05
VLAI
Title
Incomplete protection against CVE-2025-11226
Summary
ACE vulnerability in conditional configuration file processing by QOS.CH logback-core up to and including version 1.5.36 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.
Please note that in logack version 1.5.37 conditional processing using Janino was removed.

CVE-2026-1225 (GCVE-0-2026-1225)

Title
Malicious logback.xml configuration file allows instantiation of arbitrary classes
Summary
ACE vulnerability in configuration file processing by QOS.CH logback-core up to and including version 1.5.24 in Java applications, allows an attacker to instantiate classes already present on the class path by compromising an existing logback configuration file.
The instantiation of a potentially malicious Java class requires that said class is present on the user's class-path. In addition, the attacker must have write access to a
configuration file. However, after successful instantiation, the instance is very likely to be discarded with no further ado.

Title
Conditional processing of logback.xml configuration file, in conjuction with Spring Framework and Janino
Summary
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-2024-12798 (GCVE-0-2024-12798)

Title
JaninoEventEvaluator vulnerability
Summary
ACE vulnerability in JaninoEventEvaluator by QOS.CH logback-core
upto including version 0.1 to 1.3.14 and 1.4.0 to 1.5.12 in Java applications allows
attacker to execute arbitrary code by compromising an existing
logback configuration file or by injecting an environment variable
before program execution.
Malicious logback configuration files can allow the attacker to execute
arbitrary code using the JaninoEventEvaluator extension.
A successful attack requires the user to 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.

Title
Incomplete protection against CVE-2025-11226
Summary
ACE vulnerability in conditional configuration file processing by QOS.CH logback-core up to and including version 1.5.36 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.
Please note that in logack version 1.5.37 conditional processing using Janino was removed.

Title
Malicious logback.xml configuration file allows instantiation of arbitrary classes
Summary
ACE vulnerability in configuration file processing by QOS.CH logback-core up to and including version 1.5.24 in Java applications, allows an attacker to instantiate classes already present on the class path by compromising an existing logback configuration file.
The instantiation of a potentially malicious Java class requires that said class is present on the user's class-path. In addition, the attacker must have write access to a
configuration file. However, after successful instantiation, the instance is very likely to be discarded with no further ado.

Title
Conditional processing of logback.xml configuration file, in conjuction with Spring Framework and Janino
Summary
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.

Title
JaninoEventEvaluator vulnerability
Summary
ACE vulnerability in JaninoEventEvaluator by QOS.CH logback-core
upto including version 0.1 to 1.3.14 and 1.4.0 to 1.5.12 in Java applications allows
attacker to execute arbitrary code by compromising an existing
logback configuration file or by injecting an environment variable
before program execution.
Malicious logback configuration files can allow the attacker to execute
arbitrary code using the JaninoEventEvaluator extension.
A successful attack requires the user to 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.
