Is this vulnerability remotely exploitable?

Yes, it can be exploited remotely through the Piwigo web service interface or any feature that issues `pwg.users.getList` calls, provided the attacker can authenticate as an administrator and reach the endpoint over the network.

Does an attacker need special access to exploit this issue?

Yes. Exploitation requires valid administrator-level credentials or an account with equivalent privileges that can invoke `pwg.users.getList` with a controlled `filter` parameter.

What is the safest general fix pattern for this type of bug?

The safest fix pattern is to replace all string-concatenated SQL with parameterized queries, restrict filterable fields and operators to a predefined whitelist, and ensure that query-building logic does not directly embed raw user input into SQL statements.
