## What is CVE-2025-52586?

CVE-2025-52586 is a high-severity vulnerability in EG4 12000XP, published on 8 Aug 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The MOD3 command traffic between the monitoring application and the 
inverter is transmitted in plaintext without encryption or obfuscation. 
This vulnerability may allow an attacker with access to a local network 
to intercept, manipulate, replay, or forge critical data, including 
read/write operations for voltage, current, and power configuration, 
operational status, alarms, telemetry, system reset, or inverter control
 commands, potentially disrupting power generation or reconfiguring 
inverter settings.

Weakness: CWE-319 (Cleartext Transmission of Sensitive Information)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
