Published by the GitHub Advisory Database at 16 Oct 2025, 15:30 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `org.springframework:spring-websocket` (Maven): affected `>=6.2.0, <6.2.12 || >=6.1.0, <=6.1.21 || >=6.0.0, <=6.0.23 || <=5.3.39`; fixed in `6.2.12`

## Machine-written summary

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

> The spring-websocket package is affected in versions 6.2.0 to before 6.2.12, 6.1.0 through 6.1.21, 6.0.0 through 6.0.23, and 5.3.39 and earlier. A security bypass in STOMP over WebSocket applications lets an attacker send unauthorized messages, and the source gives few details on the conditions required. Upgrade to 6.2.12 or a later fixed version.

## 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-7fch-4f2f-jcgm>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
