Published by the GitHub Advisory Database at 9 Sept 2026, 17:59 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `github.com/lf-edge/ekuiper/v2` (Go): affected `<2.4.1`; fixed in `2.4.1`

## Machine-written summary

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

> eKuiper (Go package github.com/lf-edge/ekuiper/v2) versions before 2.4.1 are vulnerable to path traversal in the plugin installation endpoint, where user-supplied resource names are joined into a temporary directory path without sufficient sanitization. An attacker with access to the management APIs, or a privileged user, can delete arbitrary files or directories on the host. Upgrade to version 2.4.1 or later, which adds identifier and file name validation.

## 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-c23q-fw86-9h5x>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
