- Find every instance of Confluence you run, including the forgotten ones, and check its version against the vendor advisory.
- Apply the vendor's fix or mitigation, before August 19, 2022 if you are bound by CISA's deadline, sooner if it faces the internet.
- Assume it was tried against you already: look for signs of exploitation from the date it was added, not from the day you patched.
