Summary
Google Chrome versions prior to 155.0.8059.39 contain a missing authorization flaw (CWE-862) in the Autofill feature. A remote attacker who uses social engineering to get a user to open a crafted HTML page can obtain sensitive information. The attack requires user interaction; NVD rates it CVSS 3.1 8.8, while Google rates it Medium.

Fixed in
- Google Chrome 155.0.8059.39 or later (Windows, Linux)
- Mac: 155.0.8059.40 or later; the vendor release notes list both .39 and .40 for Windows and Mac
Workaround
Unknown. No vendor workaround has been identified. Updating Chrome is the fix.
Exploitation
- CISA SSVC assessment: exploitation none, not automatable, partial technical impact
- EPSS 0.0032
- No public proof of concept or in-the-wild exploitation found. CISA KEV status was not verified against the primary catalog.
Our recommendation
- Verify the Chrome version on all endpoints and update to 155.0.8059.39 or later (Mac: 155.0.8059.40 or later).
- Ensure automatic updates are enabled and force updates on machines that lag behind.
- Monitor for new exploitation reports and check the CISA KEV catalog.
