What is meant by vulnerable permissions in a security system?

Vulnerable permissions in a security system are such access rights settings that grant applications or users more privileges than necessary, which can lead to unauthorized access or exploitation. In the context of Android, this often means that an application requests or obtains permissions that allow it to read or modify data, control the device, or interact with other applications without proper oversight.

For example, if an application gains permission to read SMS or access contacts without a clear need, this can be a vulnerability that an attacker could exploit to steal data or spread malicious software. Therefore, it is important to minimize and carefully control the permissions granted to applications.
