Inappropriate implementation in Speech in Google Chrome prior to 148.0.7778.96 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
UI spoofing vulnerability in Google Chrome prior to 148.0.7778.96 allows remote attackers to deceive users through crafted HTML pages that manipulate the speech interface, potentially disclosing sensitive information or causing denial of service. The vulnerability requires user interaction (clicking or interacting with the malicious page) and affects the speech component's visual presentation. Chromium severity is rated Medium; no active exploitation has been publicly confirmed.
Technical ContextAI
The vulnerability exists in Chrome's Speech component (likely the Web Speech API or speech recognition UI) where inappropriate implementation of the speech interface handling fails to properly validate or sanitize HTML content, allowing attackers to spoof legitimate UI elements. CWE-451 (User Interface (UI) Misrepresentation of Critical Information) describes the root cause: the application fails to present critical information (such as speech input dialogs, permission prompts, or status indicators) in a way that cannot be confused with attacker-controlled content. This is facilitated by inadequate isolation between user-controlled HTML and the browser's native speech UI components. The CPE string (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*) indicates all Chrome versions before the fix are theoretically affected, but the EUVD clarifies the actual vulnerable range is everything prior to version 148.0.7778.96.
RemediationAI
Vendor-released patch: Chrome 148.0.7778.96 and later. Users should immediately update Google Chrome to version 148.0.7778.96 or newer via Settings > About Chrome (automatic update) or manual download from https://www.google.com/chrome/. No workarounds are available for this vulnerability without disabling the speech feature entirely, which is not recommended. Enterprise administrators can enforce automatic updates via Chrome policies or push updates through device management solutions. The patch is confirmed available per Chrome security advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop.html.
