On we learned via EPS that there is a security vulnerability in their app PTC & STC Insight Extension for Confluence Server related to Log4Shell (CVE-2021-44228). We urge our customers to deactivate the app for the moment until a new release with fix is available.
Our cloud apps are not affected by Log4, however our PTC server/datacenter app is. We are working on a hotfix and will release it as soon as possible.
