### GitHub Vulnerability Alerts

#### [CVE-2024-12798](https://nvd.nist.gov/vuln/detail/CVE-2024-12798)

ACE vulnerability in JaninoEventEvaluator by QOS.CH logback-core up to
and including version 1.5.12 in Java applications allows attackers 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.

#### [CVE-2024-12801](https://nvd.nist.gov/vuln/detail/CVE-2024-12801)

Server-Side Request Forgery (SSRF) in SaxEventRecorder by QOS.CH logback
version 1.5.12 on the Java platform, allows an attacker to forge
requests by compromising logback configuration files in XML.
 
The attacks involves the modification of DOCTYPE declaration in  XML
configuration files.
