Google Chrome: Incorrect authorization in Browser allows information disclosure
Summary
Google Chrome versions before 155.0.8059.39 contain an incorrect authorization flaw in the Browser component. A remote attacker can obtain sensitive information if a user opens a crafted HTML page. No attacker privileges are required, but user interaction is. Chromium rates the issue as Low severity, while NVD scores it 8.8 (High).
Affected
- Google Chrome prior to 155.0.8059.39
- Other Chromium-based browsers and Linux packages depend on their own vendor releases; check their versions separately.
Fixed in
- Google Chrome 155.0.8059.39 or later (Windows and Mac: 155.0.8059.39/.40 per the Google advisory; Linux: 155.0.8059.39)
- Android: version 155.0.8059.39 is reported to be rolling out to a small percentage of users; check the Google Play listing.
Workaround
- No workaround is documented.
- Updating Chrome is the practical mitigation.
Exploitation
- Not listed in CISA KEV; no known exploitation reported.
- CISA SSVC: exploitation none, automatable no, technical impact partial.
- No public proof of concept found in the searches performed.
Our recommendation
- Update Chrome to 155.0.8059.39 or later on all endpoints and relaunch the browser.
- Verify the installed version across the fleet instead of assuming automatic updates have applied.
- Check and update other Chromium-based browsers and Linux packages.
- Treat the release as a batch: it also fixes further security issues, including Critical ones.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
