Insufficient policy enforcement in WebHID in Google Chrome prior to 150.0.7871.47 allowed an attacker who convinced a user to install a malicious extension to perform privilege escalation via a crafted Chrome Extension. (Chromium security severity: Medium)
AnalysisAI
Privilege escalation in Google Chrome desktop prior to 150.0.7871.47 stems from insufficient policy enforcement in the WebHID subsystem, letting a maliciously crafted extension escape its intended boundaries and gain elevated access to human-interface devices and browser privileges. Exploitation first requires convincing a victim to install the malicious extension, after which a crafted Chrome Extension bypasses WebHID access controls. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to install an attacker-controlled Chrome Extension - this installation step is the primary concrete prerequisite drawn directly from the description ('convinced a user to install a malicious extension'). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed and should be weighed against the raw 8.1 score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker publishes a seemingly benign browser extension (or compromises an existing one) and social-engineers a target into installing it. Once installed, the extension issues crafted WebHID calls that bypass Chrome's policy enforcement to access devices or browser privileges it should not have, escalating from extension-sandbox privileges toward fuller compromise of the browser session and connected HID devices. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later on all desktop platforms; most installations update automatically, so relaunch the browser to apply the update and confirm via chrome://settings/help. … Detailed patch versions, workarounds, and compensating controls in full report. |
