Detailsinfo

A vulnerability classified as problematic has been found in Datadog Android App up to 5.9.1. Affected is the function FirebaseCrashlytics.setUserId of the component Firebase Crashlytics Integration. The manipulation of the argument uuid with an unknown input leads to a private personal information vulnerability. CWE is classifying the issue as CWE-359. The product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected. This is going to have an impact on confidentiality. CVE summarizes:

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.

The advisory is available at trust.datadoghq.com. This vulnerability is traded as CVE-2026-47364 since 05/19/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1589 by the MITRE ATT&CK project.
