Microsoft ships Edge 150.0.4078.50 security update for Android and iOS

Microsoft has released a new security update for the mobile editions of Edge, moving the Android and iOS browser to version 150.0.4078.50. The July 6 release note says the update incorporates the latest security updates from the Chromium project, while Microsoft adds that CVE details will be published when they are available.

The timing makes the release relevant even without a finalized CVE list. Mobile browsers now sit in the middle of sign-in flows, passkey prompts, corporate identity portals, webmail, collaboration tools, and payment pages. A security-only browser update can therefore matter to both individual users and managed-device fleets, especially where employees use phones as their primary work device or as a second screen for authentication.

What is known

• Microsoft identifies the affected product as Microsoft Edge for Android and iOS.
• The updated mobile version is 150.0.4078.50.
• The release was posted on July 6, 2026.
• Microsoft says the update pulls in current Chromium security updates.
• The company has not yet listed the related CVEs in the release note.

That last point is important for how security teams should read the notice. The absence of listed CVEs does not mean the update is cosmetic; it means Microsoft has not yet attached the identifiers to the public release note. Browser vendors often restrict or stage vulnerability details while patches are still rolling out, because bug reports can help attackers understand where to look before most users have updated.

For consumers, the practical action is simple: check the App Store or Google Play for the latest Edge update and let automatic updates complete. For organizations, the update is a reminder to verify mobile browser patch levels in mobile device management dashboards instead of focusing only on desktop browsers. If Edge is approved for accessing company mail, SaaS dashboards, or internal apps, mobile update compliance should be treated as part of the same browser-security program.

This release is not a claim of active exploitation, and Microsoft has not described any Edge-specific mobile vulnerability in the July 6 note. The supported takeaway is narrower but still useful: a current Edge mobile build is now available, it includes Chromium security updates, and administrators should avoid leaving mobile browsers outside their normal patch checks.
