## Affected packages

- `org.dspace:dspace-api` (Maven): affected `<7.6.7 || >=8.0-rc1, <8.4 || >=9.0-rc1, <9.3 || >=10-rc1, <10.0`; fixed in `7.6.7`, `8.4`, `9.3`, `10.0`

## Machine-written summary

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

> DSpace (org.dspace:dspace-api, which is Maven; the package name is dspace-api) versions before 7.6.7, from 8.0-rc1 before 8.4, from 9.0-rc1 before 9.3, and from 10-rc1 before 10.0 do not validate the URI scheme of ORE resources ingested by URI. An attacker who already holds collection, community or site administrator rights, or a compromised remote OAI endpoint, can supply ORE XML that causes a local server file to be ingested as a bitstream, exposing local file data. Upgrade to DSpace 7.6.7, 8.4, 9.3 or 10.0, or disable the ORE ingestion crosswalk in the configuration.

## 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-c827-pw3m-67w7>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
