Is this vulnerability remotely exploitable?

Yes, it can be exploited remotely via HTTP requests, provided the attacker can reach and invoke the PostCalendar administrative `categoriesUpdate` endpoint that processes the `dels` parameter.

Does an attacker need authentication or special privileges?

In typical deployments, access requires an authenticated user with permissions to manage PostCalendar categories (often an admin or privileged staff role). However, the practical impact depends on how tightly these permissions are controlled and whether such accounts can be compromised.

What is the safest general fix pattern for this issue?

The most robust fix is to replace all string-concatenated SQL in the affected path with parameterized queries, passing the `dels` value (and similar inputs) as bound parameters through the database abstraction layer rather than interpolating it into SQL strings.
