If you'd like to detect whether you're affected by this dynamically, it looks like https://github.com/google/tsunami-security-scanner-plugins/i... will eventually make it into Google's dynamic scanner: https://github.com/google/tsunami-security-scanner (I bet it would be easy to write a plugin for https://github.com/projectdiscovery/nuclei as well.)

To see if there are injection points statically, I work on a tool (https://github.com/returntocorp/semgrep) that someone else already wrote a check with: https://twitter.com/lapt0r/status/1469096944047779845 or look for the mitigation with `semgrep -e '$LOGGER.formatMsgNoLookups(true)' --lang java`. For the mitigation, the string should be unique enough that just ripgrep works well too.
