Is this vulnerability remotely exploitable, or does it require local access?

It is remotely exploitable through the web interface as long as the attacker can authenticate to the application; no local system access is required.

What level of access does an attacker need to exploit this issue?

Any basic authenticated user account is sufficient. The attacker does not need administrative rights, membership in the target team, or existing ownership of that team.

What is the safest general fix pattern for this vulnerability class?

Centralize and enforce strict server-side authorization for all sensitive operations, particularly ownership and permission changes. Ensure that the application always verifies the requester's role and relationship to the resource before performing the requested action, and avoid relying on client-provided identifiers as proof of authorization.
