GHSA-98mx-cjp9-gchm Electron: Extension tabs.query returns tab URLs and titles without the tabs permission

• npm electron: >= 45.0.0-alpha.1, < 45.0.0-alpha.4 → fixed in 45.0.0-alpha.4 • npm electron: >= 44.0.0-alpha.1, < 44.1.1 → fixed in 44.1.1 • npm electron: >= 43.0.0-alpha.1, < 43.5.1 → fixed in 43.5.1 • npm electron: < 42.11.1 → fixed in 42.11.1

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` For more information If you have any questions or comments about this advisory, email us at [email protected]
