Summary

A remote attacker who uses social engineering can get a user to open a crafted HTML page and obtain sensitive information. Chromium rates the issue Medium; the NVD score is 8.8, but the described impact is limited to information disclosure.
Affected

- The CVE record's version range is internally inconsistent; the description is used here.
Fixed in
- Google Chrome 155.0.8059.39 or later for macOS (the vendor's Stable Channel update of 6 October 2026 lists 155.0.8059.39/.40 for Windows and Mac)
- Later stable builds are also available; install the current stable release.

Our recommendation
- Update Google Chrome on all macOS devices to the current stable release.
- Make sure automatic updates are not blocked; enforce the update through MDM or Chrome policy in managed fleets.
- Treat this as a regular patch item, with higher priority where users handle sensitive data in the browser.
- Check that no macOS Chrome installation is outdated.
