Published by the GitHub Advisory Database at 6 Jul 2026, 16:52 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `io.openremote:openremote-manager` (Maven): affected `<1.24.1`; fixed in `1.24.1`

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Versions of io.openremote:openremote-manager before 1.24.1 let users who hold only read:assets privileges write predicted datapoints for assets, which should require write:assets. An attacker with a read-only asset account can therefore modify predicted datapoint values. Upgrade to openremote-manager 1.24.1 or later.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-xj53-j257-hxvg>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
