Update to 2.15 is not sufficient due to https://nvd.nist.gov/vuln/detail/CVE-2021-45046, it requires 2.16.
This one is less important but will still be detected by scanners and alert all users.
As released 1 Aug 2023, testdroid-run-in-cloud plugin now includes log4j 2.17.2 in its hpi file instead of including earlier versions.
It includes many more jar files in the plugin hpi file than are actually needed (including guava and jsr305 and httpclient-4.5.14 and ...), but as far as I can tell, those unnecessary jar files are not what this issue was reporting.
