## Machine-written summary

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

> Wagtail (PyPI package wagtail) versions 7.0.9 to before 7.1, 7.1rc1 to before 7.3.4, 7.4rc1 to before 7.4.3, and 8.0rc1 before 8.0rc2 are affected. A CMS user who has the "submit translations" permission can use the Admin API's "copy for translation" endpoint to copy an existing page they do not have edit access to, which lets them view that page's contents. Upgrade to Wagtail 7.0.9, 7.3.4, 7.4.3, or 8.0rc2, depending on the release line in use.

## 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-jm5p-837g-rv8g>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
