Find Vulnerabilities in Your React Native App Before Attackers Do

Start with a free check of your dependencies against published advisories. Then have senior engineers audit what a scanner cannot see.

Security audits from engineers shipping React Native since 2016.

Start with the free scan. Book the audit if you want us to fix what we find.

What We Check

🔒

Dependency & CVE Exposure

We audit your full dependency tree for known vulnerabilities, in both direct and transitive packages, and assess which matches are reachable in your app before ranking them.

Cross-referenced against OSV.dev, NIST NVD, and the GitHub Advisory Database.

🔄

Version Drift & Risky Libraries

Outdated React Native versions, stale native modules, and libraries with known compatibility issues that create silent breakage and security gaps.

Reference: React Native release support policy (the latest 3 minor series are maintained) · React Native Upgrade Helper.

🛠

Build & Release Configuration

Debug settings or cleartext exceptions in release builds, sensitive data in logs, and R8 configuration, with obfuscation assessed as defense in depth for your threat model.

Reference: Android R8/ProGuard guidance · OWASP MASVS.

🔗

Supply-Chain Risk

Abandoned packages, single-maintainer dependencies, and libraries with suspicious update patterns that could become attack vectors.

Reference: GitHub Advisory Database · OSV.dev · CISA/NSA Securing the Software Supply Chain.

📱

iOS & Android Build Pipeline

High-level review of your native build configs, signing setup, ATS/cleartext settings, and platform-specific security flags.

Reference: Apple App Transport Security · Android Network Security Configuration.

Sample Security Findings

Illustrative example with made-up findings. Not from a real client.

Each finding separates the evidence, the advisory's own severity where there is one, and our priority for this particular app. Severity describes a vulnerability in general; priority depends on whether it is reachable and what it exposes.

ExampleApp (payments) Security Audit — Illustrative
Secret payments API key in the release JavaScript bundle Priority: High

Evidence: the key is set through react-native-config and appears in plain text in the shipped bundle.

Fix: rotate the key now, then move the calls that need it to the backend and give the app short-lived, per-user tokens. Moving the key into Keychain would not help, because it would still ship with the app.

Refresh token stored in AsyncStorage Priority: Medium

Evidence: the token is readable in the app's unencrypted Async Storage data on a test device.

Fix: store tokens with Keychain and Keystore-backed storage (react-native-keychain or expo-secure-store) and remove the old entry on upgrade.

minimist 1.2.5 matches GHSA-xvch-5gv4-984h Advisory: Critical Priority: Low

Evidence: the advisory's affected range is >=1.0.0 <1.2.6. In this app the package is only used by a build script; it is not in the shipped bundle and never parses user input.

Fix: move to 1.2.6 or later through the parent package at the next routine dependency update.

React Native 0.68 is unsupported Planning

Evidence: 0.68 is outside the officially supported releases. Being unsupported is not a vulnerability by itself; no finding in this audit traces to React Native core. The risk is that future fixes won't be released for this version.

Fix: plan an upgrade to a supported release. It crosses the New Architecture boundary at 0.82, so scope it as a migration.

3 dependencies without a release in over 2 years Planning

Evidence: none matches a published advisory, but two block the React Native upgrade.

Fix: replace them or take over maintenance as part of the upgrade plan.

No certificate pinning Not needed here

Evidence: traffic is HTTPS-only with App Transport Security and Android's cleartext defaults intact. Pinning is a threat-model decision, and Apple and Android both advise against it in most cases.

No change. If the threat model changes, pin public keys with backup pins and a rotation plan.

Release build configuration Pass

Evidence: release builds use the release configuration, and cleartext exceptions exist only in debug configuration.

Fix first: Rotate the exposed API key.

Audit Process

1

Intake + Scope

Share your repo via secure access. We sign NDAs before touching any code, define the audit scope, and work in isolated environments.

2

Analysis + Validation

We audit dependencies, secrets, network security, storage, build config, and native pipelines. Every finding is manually reviewed, with evidence, before it goes in the report.

3

Report + Remediation Plan

You get a detailed report with severity ratings and a prioritized fix plan. We can implement the fixes or hand the plan to your team.

Frequently Asked Questions

What does a React Native security audit include?

Our full manual audit covers dependency CVE review, secrets and credential auditing, network security assessment (TLS configuration, cleartext traffic, and whether certificate pinning fits your threat model), local storage and encryption review, build configuration analysis (debug flags, R8/ProGuard settings), deep link and WebView security, and supply chain risk. You receive a detailed report with severity ratings and a prioritized fix plan.

How long does a React Native security audit take?

A full manual security audit typically takes 5–10 business days from codebase access to final report delivery, depending on codebase size and complexity.

Do you sign an NDA before accessing our code?

Yes. We sign NDAs before accessing any code. We request controlled repository access and work in isolated environments. All findings are kept strictly confidential.

What's the difference between the free scanner and the full manual audit?

The free scanner checks the installed package versions in your lockfile against published npm security advisories. It does not look at your code. The manual audit is conducted by senior engineers who review your entire codebase: dependencies, secrets, network security, storage, build configuration, and native platform specifics. The manual audit catches issues the automated scan cannot.

Can you fix the vulnerabilities you find?

Yes. We can implement the fixes as part of the engagement, or your team can work from the prioritized plan in the report.

What compliance requirements does your audit support?

Findings map to OWASP MASVS and the OWASP Mobile Top 10 (2024). Teams often use the report and its remediation record as evidence in SOC 2, ISO 27001, and enterprise security reviews, but the audit is not a compliance certification.
