Official description

NVD · unedited

In versions of the Datadog Android application prior to v545-5.9.2, the app tags Crashlytics data with the user's Datadog UUID, with no user-facing opt-out. Impact: The Datadog user UUID and crash data are visible within Firebase Crashlytics. This UUID is not identifying outside Datadog's own systems.

Technical summary

dbcve analysis

How this class of weakness works · CWE-200

The application discloses data — error detail, internal paths, tokens, or other users' records — to someone who shouldn't see it. On its own it can look minor, but it hands attackers the map they need for a larger attack. Remediation is about minimising what's returned and enforcing authorization on every piece of data.

From vendor data

No vendor fix exists The vendor has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.

If you're using Datadog's SDK in a mobile app alongside Firebase Crashlytics, crash reports sent to Firebase may contain a Datadog user identifier that users never consented to share with Google's infrastructure. This isn't a hypothetical privacy concern—it is an active data flow that creates cross-service identity linkage without user knowledge or control. Check your Firebase Crashlytics console for any UUID-like fields or unexpected identifiers in crash payloads. Compare these against the user IDs your Datadog SDK configuration generates. If you see correlation between the two, your users' crash behavior is now linkable to their Datadog identity within a system (Firebase) that operates under a different privacy policy with different retention assumptions. The isolation users expect between distinct telemetry vendors is broken. The structural problem here is that SDK vendors treat cross-service data flows as an implementation detail. Datadog's SDK likely passed a user-context object to its crash reporting module, which then transmitted that context to Firebase's Crashlytics endpoint. No opt-out mechanism existed, and the documentation likely never warned developers that this linkage would occur. You cannot consent to what you don't know is happening. Audit your SDK integration for similar patterns. Map every telemetry SDK you bundle and ask: what identifiers does each one generate, and which third-party endpoints receive them? The answer is almost certainly not documented in any integration guide. Treat this as a class of consent failures that will become more visible as auditors examine SDK-to-SDK data flows. The fix from Datadog likely addresses this specific vector, but the architectural pattern—shared user context objects propagating across integration surfaces—likely persists in other pathways within the SDK. Monitor for subsequent disclosures. The EPSS score of 0.00251 reflects low active exploitation, but that metric measures exploitability of a defined vulnerability, not the blast radius of a data architecture failure. The real exposure is the compound risk: users have behavioral profiles (crash patterns, session timing, error frequency) linked across systems they never consented to link, with no mechanism to request deletion or opt out.

Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
