Hi,

The following vulnerability was published for logback.

CVE-2024-12798[0]:
| ACE vulnerability in JaninoEventEvaluator  by QOS.CH logback-core
| upto and including version 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.

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

Fix: CVE-2024-12801 - Server-Side Request Forgery (SSRF) in
SaxEventRecorder by QOS.CH logback version 0.1 to 1.3.14 and 1.4.0 to
1.5.12  on the Java platform, allows an attacker to forge requests by

On the 1.5.x series
The 1.5.x series is a direct descendant of and a drop-in replacement for
the 1.4.x series. It differs from the 1.4.x series by the relocation of
the logback-access module which was moved to its own separate github
repository.
Here is a summary of 1.5.x dependencies:

Let me know if you have any questions.
