Is this vulnerability remotely exploitable?

Yes, if an attacker can reach the `/tabs/action` endpoint over the network. The exact exposure depends on your deployment and whether the endpoint is accessible from untrusted networks or only from authenticated users.

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

The attacker needs the ability to issue requests to the affected tab action routes. In some environments this might require valid application credentials or a compromised user account; in others, misconfiguration could expose the endpoint more broadly.

What is the safest general fix pattern?

The most robust fix is to route all tab-related operations through a centralized authorization and SSRF enforcement layer. Every call that can influence browser navigation should explicitly verify the caller's permissions and confirm that the requested target complies with the configured SSRF policy.
