CVE-2026-47363
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.
What this means for your business
