Is this vulnerability remotely exploitable?

Yes. Any attacker who can reach the `/vae-api` or `/caption-api` endpoints and send crafted HTTP requests can potentially exploit this issue.

What level of access does an attacker need?

The attacker typically only needs network access to the exposed endpoints; no local system access is required, and authentication requirements depend on how the service is deployed.

What is the safest general fix pattern?

Replace pickle-based deserialization for incoming requests with a safe, data-only serialization format (such as JSON) and enforce strict schema validation on all fields before processing.
