I cover the Log4j2 vulnerability affecting every Tableau product and explain why you must update or uninstall older versions immediately. I walk through which builds have been patched, the quirks of Tableau Prep versioning, and the alternatives if you can't update straight away.

## Key takeaways

- Every Tableau product is affected by the Log4j2 remote code execution vulnerability, including Desktop, Public, Reader, Online, Server and Prep Builder across Windows, Mac and Linux.
- You must be on the build released on 15th December 2021 to be patched, not just on 2020.4 generally; versions 2020.3 and older are past end of maintenance and will not be patched.
- Tableau Prep treats every release as a patch, so your only fix is to upgrade to the latest version (2021.4.1), not stay on an older build.
- Tableau's knowledge base offers manual mitigation steps, but they need admin rights and are hard to maintain, so updating is by far the easiest route.
- Uninstall old versions entirely; leaving them on your laptop keeps you exposed, as a targeted workbook could compromise your machine and reach your server and data.
