High advisory for OpenRemote

Advisory overview

OpenRemote is an open-source internet-of-things platform. Prior to 1.26.0, the `datapoint export` API constructs `CSV crosstab` SQL by concatenating an `asset name` and `attribute name` into a `COPY` query that uses `crosstab` and streams `TO STDOUT`. The `asset name` enters both a double-quoted column identifier and a category query enclosed by the fixed `$cat$` delimiter. Escaping single quotes in one string context does not escape embedded double quotes in identifiers or protect that dollar-quote boundary. An authenticated user permitted to create or rename an asset and read/export datapoints for one of its attributes can store SQL metacharacters in the name and request a `crosstab` export, causing injected SELECT output to be returned in the normal ZIP/CSV response. This enables database exfiltration without direct database or filesystem access or token forgery. In a multi-tenant deployment it can expose other tenants' data if the manager's database role can read shared tables; integrity and availability effects are not established by the demonstrated read primitive. This issue is fixed in version 1.26.0.
