Information leak in Bluetooth in Google Chrome on on Mac prior to 152.0.7977.65 allowed a remote attacker who had compromised the renderer process and leveraged social engineering to obtain sensitive information via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Bluetooth information disclosure in Google Chrome on macOS (versions prior to 152.0.7977.65) enables a remote attacker - who has already compromised the renderer process - to extract sensitive Bluetooth-related information by combining a crafted HTML page with social engineering. This is a chained, multi-prerequisite vulnerability: successful exploitation requires a prior renderer compromise and active victim interaction, which the CVSS AC:H rating reflects. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires two simultaneous preconditions: (1) the attacker must have already compromised the Chrome renderer process via a separate, independent vulnerability - this is not a standalone exploit; and (2) the attacker must successfully social engineer the victim into interacting with a crafted HTML page (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is low despite the C:H CVSS confidentiality rating. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already exploited a separate Chrome renderer vulnerability on a macOS target crafts a malicious HTML page designed to invoke Bluetooth APIs from the compromised renderer context. They then use social engineering - such as a deceptive prompt or redirect - to induce the victim to interact with the page, triggering the information leak and exposing Bluetooth device information back to the attacker. … |
| Remediation | Upgrade Google Chrome on macOS to version 152.0.7977.65 or later, which includes the vendor-released patch per the Chrome stable channel update advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
