Use after free in CameraCapture in Google Chrome on Mac prior to 149.0.7827.103 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox escape in Google Chrome for Mac (versions prior to 149.0.7827.103) stems from a use-after-free condition in the CameraCapture component, enabling a remote attacker to break out of the renderer sandbox via a crafted HTML page. With a CVSS of 9.6 (scope-changed, high impact across CIA) and an upstream fix released by Google, the bug carries high severity but requires user interaction to load the malicious page; no public exploit identified at time of analysis.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Target must be running Google Chrome on macOS at a version below 149.0.7827.103, and the victim must perform user interaction by loading attacker-controlled HTML in that browser (UI:R in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are largely aligned toward serious risk: CVSS 9.6 with AV:N/AC:L/PR:N/S:C/C:H/I:H/A:H indicates a low-complexity, network-reachable, unauthenticated attack with cross-component impact, and the affected primitive (sandbox escape) is exactly the class Google rates 'High' internally. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious HTML page (or injects it via a malvertising chain) that, when visited by a Mac user running an unpatched Chrome, drives the WebRTC/getUserMedia surface in a way that triggers the use-after-free in CameraCapture. By spraying the freed allocation with attacker-controlled data the attacker corrupts a freed object's vtable or callback pointer, gaining code execution that escapes the renderer sandbox (S:C in the CVSS vector) and runs in a more privileged Chrome process context. … |
| Remediation | Primary fix: upgrade Google Chrome on macOS to 149.0.7827.103 or later (vendor-released patch confirmed by Google via the Chrome Releases Stable Channel post at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html); on managed fleets, force-restart Chrome so the staged update actually loads. … Detailed patch versions, workarounds, and compensating controls in full report. |
