workarounds: value: You must revoke all active integration API keys to fully mitigate the impact of this issue.

To revoke integration API keys from the Cortex XSOAR web client:
Settings > Integration > API Keys  and then Revoke each API key.

You can create new API keys after you upgrade Cortex XSOAR to a fixed version.
value: Restricting network access to the Cortex XSOAR server to allow only trusted users also reduces the impact of this issue.
