AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
Attacker must already control the renderer (PR:L) and groom the heap (AC:H) while the victim loads malicious content (UI:R); sandbox escape crosses a trust boundary (S:C) with full host impact.

Use after free in Navigation in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox escape in Google Chrome's Navigation component (versions prior to 151.0.7922.72) lets an attacker who has already compromised the renderer process break out of the browser sandbox via a crafted HTML page, escalating a renderer-level foothold toward host-level code execution. Chromium rates the security severity High and the CVSS is 8.3; no public exploit identified at time of analysis, and the EPSS probability is low at 0.29% (21st percentile). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has ALREADY compromised the Chrome renderer process - this is explicitly stated and is the hard gating prerequisite; the bug is a sandbox-escape stage, not an initial-access vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed and should be read together. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first compromises the Chrome renderer using a separate bug (or a chained primitive), then serves a crafted HTML page that drives Navigation into a use-after-free, corrupting browser-process state to escape the sandbox and gain higher-privileged code execution on the host. Realistically this is delivered via a malicious or compromised website that the victim visits (UI:R), and the high attack complexity (AC:H) means reliable exploitation requires precise heap grooming. … |
| Remediation | Vendor-released patch: Google Chrome 151.0.7922.72 (or later) on the Stable channel - update Chrome and relaunch so the new version takes effect, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
