Security readout for executives and security teams
Plain-English summary
CVE-2022-3047 is a Chrome Extensions API policy enforcement flaw. If a user installed a malicious extension, the attacker could use a crafted HTML page to bypass Chrome download policy controls. The main business risk is integrity of browser-enforced download restrictions, not direct data theft or service outage.
Executive priority
Prioritize as routine but important browser fleet remediation. Escalate in environments that allow broad extension installation or depend on Chrome download controls for compliance, malware prevention, or data handling policy enforcement.
Technical view
Google Chrome before 105.0.5195.52 had insufficient policy enforcement in the Extensions API, classified as CWE-602. The CVSS 3.1 score is 6.5 with network access, low complexity, no privileges, and user interaction required. The impact is rated high for integrity only.
Likely exposure
Exposure is most likely on endpoints running Chrome older than 105.0.5195.52, especially where users can install extensions and organizations rely on Chrome download policies.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. Exploitation requires social engineering a user into installing a malicious extension and then interacting with attacker-controlled content.
Researcher notes
The affected range is stated only as Chrome prior to 105.0.5195.52 with unspecified affected versions in the bundle. Public details are limited; avoid inferring exploit mechanics beyond malicious extension, crafted HTML page, and download policy bypass.
Mitigation direction
- Update Chrome to 105.0.5195.52 or later.
- Apply distribution vendor updates for packaged Chromium or Chrome builds.
- Review Chrome extension installation controls and approved-extension allowlists.
- Check Google, Gentoo, or Fedora advisories for environment-specific guidance.
Validation and detection
- Inventory Chrome versions across managed endpoints.
- Identify endpoints older than 105.0.5195.52.
- Review extension management policy for unauthorized installed extensions.
- Confirm download restriction policies remain enforced after browser updates.
