### 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 security@electronjs.org
