An improper authorization vulnerability in Palo Alto Networks Cortex XSOAR enables a remote unauthenticated attacker with network access to the Cortex XSOAR server to perform unauthorized actions through the REST API.
Work around:
Until the XSOAR server is upgraded, to completely prevent the issue from being exploited, you must revoke all active integration API keys as a workaround.
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.
