Support: Apache Log4j Vulnerability

We are aware of the security advisories regarding the Apache Log4j Vulnerabilities announced between December 9th, 2021 and December 27th, 2021. More information can be found here:

We have determined that there is a very low risk to PrizmDoc Viewer customers using PrizmDoc Viewer version 13.5 or newer.  However, out of an abundance of caution, we strongly recommend that customers update their installation of PrizmDoc Viewer to version or later which has the latest version of Log4j.

Although the impacted version of Log4j is shipped with our product, it is mitigated because we do not write user-supplied data to our logs therefore an RCE attack is almost impossible.

If you are running a PrizmDoc Viewer/Server prior to 13.5 (November 2018) you should upgrade immediately to the most recent version. Version upgrades in 13.x are backwards compatible and do not require code changes to support the backend upgrade. If you have concerns, please contact Accusoft support or

In accordance with our security vulnerability policy, the official PrizmDoc Viewer version 13.19 with an updated version of Log4j  is planned to release on January 25, 2022.
