## Affected packages

- `github.com/hashicorp/vault` (Go): affected `>=1.2.0, <1.18.1`; fixed in `1.18.1`
- `github.com/openbao/openbao` (Go): affected `<2.0.3`; fixed in `2.0.3`

## Machine-written summary

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

> Hashicorp Vault versions 1.2.0 up to 1.18.1 and OpenBao versions before 2.0.3 are vulnerable when they use the Integrated Storage backend. An attacker who can send a large volume of requests to the Raft cluster join API endpoint can exhaust system memory, potentially crashing the server. Upgrade Vault to 1.18.1 or OpenBao to 2.0.3; the source also lists fixed Vault Enterprise releases 1.17.8 and 1.16.12.

## 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-g233-2p4r-3q7v>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
