Analysis

Impact

The vulnerability resides in the syncInvoke function of the WebView JS Bridge inside the SHAREit App. By manipulating inputs, an attacker can call an exposed dangerous routine from outside the app, which the component processes without adequate validation. The flaw, identified as CWE‑749, can allow the attacker to trigger privileged operations or execute arbitrary code, thereby compromising the device.

Affected Systems

Smart Media4U Technology SHAREit App version 6.27.38_ww running on Android devices is affected. The issue appears in this specific version of the app and relates to the use of an exposed WebView JS Bridge.

Risk and Exploitability

The CVSS score of 6.9 indicates a medium severity. EPSS data is not available, but the vulnerability has been publicly disclosed, suggesting that attackers may craft a remote payload. It is not listed in the CISA KEV catalog, yet exploitation is possible over the network by sending crafted messages to the syncInvoke routine. The overall risk is moderate, and because the vendor has not released a fix, continuous monitoring is advised.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
