Google Chrome: Improper input validation in Input component
Summary
Google Chrome versions before 156.0.8078.47 contain an improper input validation flaw in the Input component. A remote attacker can use a crafted HTML page to potentially execute arbitrary code inside the browser sandbox. No user interaction beyond visiting the page is required according to the CVSS vector, which is rated UI:R, so a victim must still open the page.
Affected
- Google Chrome (desktop) prior to 156.0.8078.47
Fixed in
- Google Chrome 156.0.8078.47 or later (desktop)
Workaround
- No vendor workaround known. Updating Chrome is the fix.
Exploitation
- No evidence of active exploitation known.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- Chromium security severity: Medium.
Our recommendation
- Update Google Chrome to version 156.0.8078.47 or later on all desktop systems.
- Verify the installed version on managed devices and enforce automatic updates.
- Check whether Chromium-based browsers in use (e.g. Microsoft Edge) are updated too.
- Check the Linux distribution or snap channel for Chromium packages.
