## Affected packages

- `Umbraco.Cms` (NuGet): affected `>=14.0.0--preview004, <14.3.4 || >=15.0.0-rc1, <15.3.1`; fixed in `14.3.4`, `15.3.1`

## Machine-written summary

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

> Umbraco.Cms versions from 14.0.0-preview004 up to 14.3.4 and from 15.0.0-rc1 up to 15.3.1 are vulnerable. An authenticated user of the Umbraco backoffice can send crafted management API requests that use path traversal to upload files to an unintended location. Upgrade to 14.3.4 or 15.3.1. As a workaround, restrict the allowed upload file extensions in the content settings to only those that are necessary.

## 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-q62r-8ppj-xvf4>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
