CVE-2026-44964 (GCVE-0-2026-44964)

Vulnerability from cvelistv5 – Published: 2026-08-07 18:02 – Updated: 2026-08-08 01:05

Summary

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.

Severity

Vulnerability from github – Published: 2026-08-07 18:31 – Updated: 2026-08-07 21:30

Details

The OnCallNotificationActivity in the Datadog Android application is declared android:exported="true" in AndroidManifest.xml with no permission guard. Any co-installed application on the same device can launch it with attacker-controlled Intent extras: on_call_page_content (rendered as full-screen lock-screen text), page_id (used to enqueue an on-call Acknowledge worker), and on_call_page_intent, a Parcelable Intent that is passed through to startActivity from inside the Datadog process after a single user tap on the Acknowledge button. The activity enables lock-screen display (setShowWhenLocked) and wakes the device (setTurnScreenOn) on launch. After one user tap, three effects follow: (1) a forged Acknowledge request is sent to the Datadog backend for the attacker-chosen page_id using the victim's authenticated session; (2) the attacker-controlled Intent is launched from the Datadog process via startActivity, providing reach into non-exported components of com.datadog.app (confused-deputy pattern); (3) the keyguard is dismissed and the screen turned on, usable as a social-engineering or annoyance vector. Preconditions: a malicious application co-installed on the victim device and an active Datadog session in the Android app.
