## Affected packages

- `org.open-metadata:openmetadata-service` (Maven): affected `<1.2.4`; fixed in `1.2.4`

## Machine-written summary

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

> OpenMetadata's openmetadata-service Maven package, versions before 1.2.4, is vulnerable to SpEL injection through the PUT /api/v1/events/subscriptions endpoint. An attacker who has an authenticated user account can supply a crafted expression that is evaluated before the authorization check runs, which may lead to remote code execution on the server. Upgrade openmetadata-service to version 1.2.4 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-8p5r-6mvv-2435>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
