In the eufy-security-ws add-on log, I can see this error/security warning: CVE-2023-46809: Marvin attack on PKCS#1 padding Wondering if anybody know if I should be worried or do anybody else experience the same behavior?

At the moment it does not affect the add-on and I have access to my eufy cameras in Home Assistant. But earlier the connection to the devices was broken, but a restart of the add-on fixed that, which was why I noticed this warning in the first place.

This is not an error, it is more an information and it is less bad than it sounds.

Due to the fact, that the PKCS#1 padding method is needed for decryption the received data, the security fix needs to be reverted. So, this message have no impact on running the client.
