We see that log4j-core-2.23.1.jar requires update in the CE and updating that jar causes an error and Orbeon fails to load.

Is there a workaround to getting log4j security issue resolved for log4j-core-2.23.1.jar

Regards,
Brian

Hi Brian,

If you're worried about Log4Shell (CVE-2021-44228), version 2.23.1 is well past that (it was fixed in 2.17), and from what I can see on the page linked below, it has no known vulnerability. Some versions released after 2.23.1 do have vulnerabilities, but none affect 2.23.1. So if your concern is specifically security, I don't see a reason to upgrade that library at this point. But please let me know if you were asking for another reason or if I misunderstood your question.

Hi Brian,

If you want to upgrade the log4j jars, you need to update all three jars (log4j-api, log4j-core, log4j-slf4j2-impl) with the same version, not just log4j-core. Does this help, or did I misunderstand your question?
