## Affected packages

- `com.haulmont.cuba:cuba-core` (Maven): affected `<7.2.23`; fixed in `7.2.23`

## Machine-written summary

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

> The cuba-core package from Maven, versions before 7.2.23, does not limit the size of files uploaded to its local file storage. An authenticated user, since the UI and generic REST API are typically restricted to logged-in users, could upload excessively large files to exhaust server disk space and cause HTTP 500 errors, leading to denial of service. Upgrade to 7.2.23 or later; alternatively, disable the Files endpoint in the application as a workaround.

## 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-w3mp-6vrj-875g>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
