GHSA-98mx-cjp9-gchm - Electron: Extension tabs.query returns tab URLs and titles without the tabs permission
### Impact
`chrome.tabs.query()` returned each tab's `url` and `title` to extensions that held neither the `tabs` permission nor matching host permissions, so any loaded extension could read the URL and title of every webContents in its session.
Apps are only affected if they load extensions (`session.extensions.loadExtension`) that they do not fully trust. Apps that load no extensions, or only trusted ones, are not affected.
### Workarounds
Do not load untrusted or unvalidated extensions. In general you should only load trusted extensions.
### Fixed Versions
* `45.0.0-alpha.4`
* `44.1.1`
* `43.5.1`
* `42.11.1`
