## Affected packages

- `github.com/siderolabs/talos` (Go): affected `<1.14.0-alpha.0.0.20260513110206-76080416beee`; fixed in `1.14.0-alpha.0.0.20260513110206-76080416beee`

## Machine-written summary

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

> Talos Linux support bundles generated by talosctl support include registry authentication credentials from RegistryAuthConfig resources, in the registryconfigs and etcfilespecs files. The Go module github.com/siderolabs/talos is affected before 1.14.0-alpha.0.0.20260513110206-76080416beee, and that version is listed as the fix. An attacker would need access to a support bundle that someone shared publicly, such as on a forum or issue tracker, and could then use the exposed credentials against the private registry. The source notes that Talos 1.14 and later encrypt support bundles by default.

## 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-7cxh-94cf-mfp6>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
