Published by the GitHub Advisory Database at 22 Oct 2026, 16:46 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `electron` (npm): affected `>=45.0.0-alpha.1, <45.0.0-alpha.4 || >=44.0.0-alpha.1, <44.1.1 || >=43.0.0-alpha.1, <43.5.1 || <42.11.1`; fixed in `45.0.0-alpha.4`, `44.1.1`, `43.5.1`, `42.11.1`

## Machine-written summary

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

> The npm package electron is affected in versions before 42.11.1, from 43.0.0-alpha.1 up to but not including 43.5.1, from 44.0.0-alpha.1 up to but not including 44.1.1, and from 45.0.0-alpha.1 up to but not including 45.0.0-alpha.4. A loaded extension without the tabs permission or matching host permissions could call chrome.tabs.query() and read the URL and title of every webContents in its session. Apps are affected only if they load extensions they do not fully trust; the fix is to upgrade to 42.11.1, 43.5.1, 44.1.1, or 45.0.0-alpha.4, and until then to load only trusted extensions.

## 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-98mx-cjp9-gchm>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
