In versions of the Datadog Android application prior to v545-5.9.2, OnCallNotificationActivity is declared exported with no permission guard. A co-installed application can launch it with attacker-controlled Intent extras, including a full-screen lock-screen message, an arbitrary on-call page ID, and an arbitrary Intent to run inside the Datadog process. This requires: A malicious application co-installed on the victim's device. An active Datadog session in the Android app. Impact: After a single tap on the Acknowledge button, the app sends a forged on-call acknowledgement to the backend under the victim's session, launches the attacker-supplied Intent from within the Datadog process (reaching otherwise non-exported components), and turns on the screen while dismissing the keyguard.
