CVE-2026-47364

In versions of the Datadog Android application prior to v541-5.9.2, the exported launcher activity AppActivity accepts an attacker-supplied session (including OAuth tokens) from Intent extras with no permission guard, and signs the app into that session without validating it against the backend. This requires a malicious application co-installed on a device with the Datadog app installed, and an OAuth token the attacker is willing to load into the victim's app. Impact: A co-installed application can switch the victim's Datadog app to a session the attacker controls. This is an account-confusion issue; it does not by itself expose the victim's existing session or data.

In Datadog Android app versions prior to v554-5.9.4, two Room-backed SQLite databases store sensitive content in plaintext: LocalNotificationDatabase (notification title, message, recipient, service, tags, and on-call/incident deep links) and SearchRecentDatabase (the user's full in-app search history).

In Datadog Android app versions prior to v541-5.9.2, BubbleChatActivity is exported with no permission guard and accepts a SEND intent with a caller-supplied conversation_id. When the activity closes and no in-process session matches that ID, it unconditionally cancels notification ID 9201 (the Bits AI chat notification), with no check on the caller's identity or ownership of the conversation.

In the Datadog Android app before v545-5.9.2, six widget configuration activities are exported without permission guards. A malicious app can exploit sequential widget IDs to hijack a user's session and display infrastructure data on screen.

In Datadog Android app versions 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.
