2DescriptionCVE.org
A vulnerability was identified in Groww Stock, Mutual Fund, Gold App up to 20260805 on Android. This affects an unknown part of the component WebView URL Handler. The manipulation leads to improper authorization in handler for custom url scheme. It is possible to launch the attack on the physical device. The complexity of an attack is rather high. It is indicated that the exploitability is difficult. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure.
AnalysisAI
Improper authorization in the WebView URL Handler of the Groww Stock, Mutual Fund, Gold App for Android (all versions up to build 20260805) allows a low-privileged attacker with physical device access to invoke custom URL scheme handlers without proper authorization, enabling unauthorized in-app navigation or bypass of client-side access controls. The CVSS 4.0 score of 0.3 reflects severe exploitation constraints: physical access is mandatory, attack complexity is high, and impact is limited to low integrity compromise with no confirmed confidentiality exposure. …

Vulnerability AssessmentAI
| Exploitation | Physical access to the target Android device is required (AV:P) - remote exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is very low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with brief physical access to an Android device where the Groww app is installed loads a crafted custom URL scheme into the app's WebView - for example, by connecting the device to an attacker-controlled system or directly interacting with an unlocked device. The WebView handler fails to verify the caller's authorization, allowing the attacker to navigate to restricted in-app screens or bypass the app's client-side lock enforcement without valid credentials. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
