Google Chrome: Missing authorization in Passwords allows site isolation bypass
Summary
Missing authorization in the Passwords component of Google Chrome on Android allows a remote attacker to bypass site isolation. The attacker must first have compromised the renderer process and then lure the user to a crafted HTML page. The flaw is a second-stage weakness in an exploit chain, and the confidentiality and integrity of data stored in the browser are at risk.
Affected
- Google Chrome on Android before 155.0.8059.39
Fixed in
- Google Chrome on Android 155.0.8059.39 or later
Workaround
- No workaround is documented. Unknown.
Exploitation
- No public proof of concept found in the sources reviewed.
- Not listed as known exploited (CISA KEV).
- EPSS score is low (about 0.2 to 0.3 percent).
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- Update Chrome on Android to 155.0.8059.39 or later, preferably the current stable branch, via Google Play.
- Use an MDM to enforce a minimum Chrome version on company Android devices.
- Prioritise devices used for privileged access or for storing business logins.
- Verify the Android build number in Google's advisory, as it could not be confirmed from the sources.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
