## Affected packages

- `org.opensearch.plugin:opensearch-security` (Maven): affected `>=1.0.0, <2.19.4.0 || >=3.0.0, <3.2.0.0`; fixed in `2.19.4.0`, `3.2.0.0`

## Machine-written summary

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

> The OpenSearch Security plugin (opensearch-security, Maven) versions 1.0.0 up to 2.19.4.0 and 3.0.0 up to 3.2.0.0 is affected. A user who already has rollover permission on a source index can roll over to a target index name they are not authorized to use, creating an index outside their allowed patterns. Upgrade to 2.19.4.0 or 3.2.0.0. As a workaround, grant the rollover permission only to fully trusted users.

## 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-22vx-2x23-98w6>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
