DescriptionCVE.org

Incorrect security UI in Contact Picker in Google Chrome on Android prior to 149.0.7827.53 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

UI spoofing in Google Chrome on Android prior to 149.0.7827.53 allows remote attackers to misrepresent the Contact Picker security UI via a crafted HTML page, potentially tricking users into disclosing contact information. Chromium rates the underlying severity as Medium, and no public exploit has been identified at time of analysis. EPSS probability is very low (0.03%), and the issue is not listed in CISA KEV.

Technical ContextAI

The flaw resides in Chrome's Contact Picker API, a web platform feature on Android that lets sites request access to selected device contacts via a browser-mediated picker UI. CWE-451 (User Interface Misrepresentation of Critical Information) indicates the picker fails to convey origin or trust context accurately, so a crafted page can manipulate the presentation of the security UI. Because Contact Picker is Android-only, the vulnerability is constrained to the Chromium Android port, specifically Chrome builds prior to 149.0.7827.53 on that platform.

RemediationAI

Vendor-released patch: Chrome for Android 149.0.7827.53 - update Chrome on Android devices to this version or later via Google Play, referencing the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html and Chromium issue https://issues.chromium.org/issues/502328201. For managed Android fleets, push the update via MDM/EMM policy and verify minimum version compliance. If patching must be delayed, a partial workaround is to disable or deny the Contact Picker permission for untrusted sites (Site Settings → Contacts) so the spoofed UI cannot extract contact data; the trade-off is that legitimate sites relying on the Contact Picker API will also be blocked. User-awareness reminders about scrutinizing picker prompts on unfamiliar sites help but are not a substitute for the update.
