Published by the GitHub Advisory Database at 16 Mar 2026, 20:47 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `github.com/akuity/kargo` (Go): affected `>=1.4.0, <1.6.4 || >=1.7.0-rc.1, <1.7.9 || >=1.8.0-rc.1, <1.8.12 || >=1.9.0-rc.1, <1.9.5`; fixed in `1.6.4`, `1.7.9`, `1.8.12`, `1.9.5`

## Machine-written summary

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

> Kargo (Go module github.com/akuity/kargo) versions 1.4.0 to before 1.6.4, 1.7.0-rc.1 to before 1.7.9, 1.8.0-rc.1 to before 1.8.12, and 1.9.0-rc.1 to before 1.9.5 are affected. The built-in http and http-download promotion steps can send requests from the controller to link-local addresses, including cloud instance metadata endpoints, which can expose credentials. An attacker with high privileges, such as permission to create or update a Stage or a Promotion, can exploit this over the network without user interaction. Upgrade to 1.6.4, 1.7.9, 1.8.12, 1.9.5, or later.

## 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-j94x-8wcp-x7hm>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
