Insufficient validation of untrusted input in Speech in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to perform UI spoofing via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
UI spoofing via the Speech component in Google Chrome prior to 150.0.7871.47 requires an attacker to have already compromised the renderer process, making this a chained, second-stage exploit rather than a standalone remote attack. The vulnerability stems from insufficient input validation (CWE-20) in Chrome's Speech subsystem, enabling a renderer-compromised attacker to manipulate browser UI elements through a crafted HTML page. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires two sequential, mandatory conditions: first, the attacker must have already achieved compromise of the Google Chrome renderer process via a separate, independent vulnerability not related to CVE-2026-14150; second, the target user must visit or interact with a crafted HTML page under the attacker's control (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is low despite the CVSS 5.4 Medium score, primarily because exploitation requires a pre-existing renderer process compromise - a high-cost prerequisite that places this vulnerability firmly in the 'chained exploit' category rather than standalone risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already achieved renderer process compromise through a separate, higher-severity vulnerability (for example, a memory corruption flaw in Chrome's JavaScript engine) serves a crafted HTML page to a targeted user. The malicious page leverages the insufficient Speech input validation to spoof browser UI elements - such as a fake security dialog or address bar content - deceiving the user into believing they are interacting with a trusted site or granting a permission they would otherwise reject. … |
| Remediation | Upgrade Google Chrome to version 150.0.7871.47 or later, which resolves this vulnerability per the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
