Is this vulnerability remotely exploitable?

Yes. Any user who can remotely authenticate to the Rocket.Chat instance and reach the API can exploit this issue, provided they know or can obtain an OAuth application ID.

What level of access does an attacker need?

Only a valid authenticated account is required. The attacker does not need administrative privileges or special roles; a low-privilege or basic user is sufficient.

What is the safest general fix pattern?

Require explicit authorization checks for reading OAuth application details, limiting full configuration (including secrets) to administrative or owner roles, and ensure that non-privileged users cannot access secret-bearing fields.
