What to do
- Apply the latest cumulative update for Power Apps immediately.
- Verify that all tenant environments are running the patched version.
- Restrict network access to Power Apps endpoints to trusted IP ranges and enforce MFA for administrative access.
- Enable logging and monitor for anomalous API calls or unexpected code execution patterns.
Mitigation status
