Security readout for executives and security teams
Plain-English summary
This ChromeOS issue could let an attacker who gets a user to interact with a malicious file gain arbitrary read/write capability on affected ChromeOS systems. That means potential compromise of data, system integrity, and device availability. The source bundle does not show active exploitation.
Executive priority
Treat as high priority for any legacy ChromeOS fleet. The impact is severe, but available evidence indicates user interaction is required and does not confirm active exploitation.
Technical view
CVE-2019-13689 is an inappropriate OS implementation in Google Chrome on ChromeOS before 75.0.3770.80. Sources describe arbitrary read/write via a malicious file. CVSS 3.1 is 7.8 high, with low complexity, no privileges, user interaction required, and high CIA impact. CWE-59 is listed.
Likely exposure
Exposure is most likely ChromeOS devices running Google Chrome/ChromeOS builds prior to 75.0.3770.80. The supplied affected data is limited, so confirm version details against Google guidance.
Exploitation context
No supplied source shows CISA KEV listing or active exploitation. The CVSS vector requires local context and user interaction, while the description references a remote attacker using a malicious file. Practical exploit maturity is not evidenced in the bundle.
Researcher notes
Source detail is limited to CVE metadata, CVSS, CWE-59, and Chromium bug references. Do not generalize this to non-ChromeOS Chrome deployments without separate vendor evidence.
Mitigation direction
- Check Google ChromeOS guidance for CVE-2019-13689.
- Update affected ChromeOS devices beyond versions prior to 75.0.3770.80.
- Prioritize managed Chromebook fleets and shared-user devices.
- Restrict handling of untrusted files where affected devices remain.
- Monitor vendor advisories for additional remediation details.
Validation and detection
- Inventory ChromeOS device versions across managed endpoints.
- Flag devices running builds prior to 75.0.3770.80.
- Confirm update status through endpoint or device management records.
- Review security logs for suspicious file-driven activity.
- Document exceptions where devices cannot be updated.
