Insufficient policy enforcement in Android intents in Google Chrome prior to 92.0.4515.107 allowed an attacker who convinced a user to install a malicious application to obtain potentially sensitive information via a crafted HTML page.

Security readout for executives and security teams

Plain-English summary

This Chrome flaw could let an attacker obtain potentially sensitive information, but only after convincing a user to install a malicious Android app and interact with a crafted web page. That multi-step requirement lowers urgency compared with direct remote browser compromise, but unmanaged Chrome versions before 92.0.4515.107 should be treated as exposed.

Executive priority

Prioritize routine-to-expedited remediation for managed Android fleets and shared-user environments. This is not evidenced as actively exploited in the provided sources, but the potential information exposure and browser footprint justify closing outdated Chrome quickly.

Technical view

CVE-2021-30580 is insufficient policy enforcement in Android intents in Google Chrome before 92.0.4515.107. The public description says a malicious installed app plus a crafted HTML page could obtain potentially sensitive information. The bundle does not provide CVSS, CWE, detailed affected ranges beyond Chrome, or root-cause detail.

Likely exposure

Exposure is most relevant to Android users running Google Chrome before 92.0.4515.107, especially where users can install untrusted applications. Fedora Chromium advisories are cited, but the bundle does not prove identical Android exposure for every Chromium-derived package.

Exploitation context

The sources do not show CISA KEV listing or active exploitation. Public evidence describes a user-assisted scenario requiring a malicious installed application and a crafted HTML page, not a standalone drive-by attack. The referenced Chromium bug may contain restricted details.

Researcher notes

Key gaps are missing CVSS, CWE, and public technical detail. The public CVE text ties impact to Android intents, a malicious installed app, and crafted HTML. Avoid assuming exploitation scope beyond Chrome before 92.0.4515.107 unless vendor advisories confirm it.

Mitigation direction

  • Update Google Chrome to 92.0.4515.107 or later.
  • Restrict installation of untrusted Android applications on managed devices.
  • Review Fedora Chromium advisories where Fedora packages are in use.
  • Check current vendor guidance for any platform-specific remediation details.

Validation and detection

  • Inventory Android devices for Chrome versions below 92.0.4515.107.
  • Confirm managed devices block or monitor untrusted app installation.
  • Check vulnerability scanners for CVE-2021-30580 findings on Chrome or Chromium packages.
  • Verify Fedora systems have applied the referenced Chromium security updates.
