AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Remote crafted page (AV:N/AC:L/PR:N) requiring the victim to open it (UI:R); a sandbox escape yields high C/I/A within the renderer's trust boundary without scope change.

Insufficient validation of untrusted input in Glic in Google Chrome prior to 150.0.7871.47 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 versions prior to 150.0.7871.47 stems from insufficient input validation in the Glic component, allowing a remote attacker who lures a victim to a crafted HTML page to potentially break out of the renderer sandbox. The flaw carries a CVSS 8.8 (High) rating and requires user interaction (visiting a malicious page); there is no public exploit identified at time of analysis and EPSS estimates only a 0.21% exploitation probability. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively open or be redirected to an attacker-controlled crafted HTML page in a vulnerable Chrome build (prior to 150.0.7871.47) - this user interaction (UI:R) is the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, score 8.8) indicates a network-reachable, low-complexity, unauthenticated attack that requires user interaction and yields high impact to confidentiality, integrity, and availability without scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page and lures a victim running a vulnerable Chrome build to visit it (via phishing link, malvertising, or a compromised site). Malformed input processed by the Glic component triggers the sandbox escape, potentially letting attacker-controlled code operate outside the renderer's isolation boundary. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later via the stable desktop channel, then relaunch the browser to complete the update (verify under chrome://settings/help). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Chrome versions deployed across the organization and identify systems running versions prior to 150.0.7871.47. …
