CVE-2026-47364
On every successful login, the Datadog Android application calls FirebaseCrashlytics.setUserId with the signed-in user's Datadog UUID — a stable per-user identifier that is meaningful inside Datadog. This associates the Datadog user UUID with the device's Firebase installation ID on Google's backend. Separately, uncaught exceptions are forwarded to Firebase Crashlytics via recordException, attaching stack traces (which may include internal class names, package names, in-flight data referenced by crash frames, and any breadcrumbs) to the same user UUID. No visible consent gate or opt-out for Crashlytics tagging was identified in the reviewed code paths. No email, name, or organization data is forwarded to Crashlytics in the reviewed paths.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
