ShineLan-X: Missing Encryption of Sensitive Data
CVE-2025-36751 is a critical-severity missing encryption of sensitive data vulnerability in ShineLan-X from Growatt, with a CVSS 4.0 base score of 9.4 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. Affected ShineLan-X versions: 3.6.0.0 through 3.6.0.2. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.08% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of ShineLan-X you run against the affected versions below, and install the vendor's latest release.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Growatt | ShineLan-X | 3.6.0.0 through 3.6.0.2 | Not stated |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.

Official description
Encryption is missing on the configuration interface for Growatt ShineLan-X and MIC 3300TL-X. This allows an attacker with access to the network to intercept and potentially manipulate communication requests between the inverter and its cloud endpoint.

The underlying weakness: Missing Encryption of Sensitive Data
The product does not encrypt sensitive or critical information before storage or transmission.
How developers prevent this class of flaw
- Clearly specify which data or resources are valuable enough that they should be protected by encryption. Require that any transmission or storage of this data/resource should use well-vetted encryption algorithms.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
- When using industry-approved techniques, use them correctly. Don't cut corners by skipping resource-intensive steps (CWE-325). These steps are often essential for preventing common attacks.
