AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
AC:H because exploitation is chained and requires a pre-compromised renderer; UI:R for the crafted media, S:C and C/I/A:H reflect the sandbox escape into the browser process.

Insufficient validation of untrusted input in Media in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted video file. (Chromium security severity: Low)
AnalysisAI
Sandbox escape in Google Chrome's Media component before version 150.0.7871.47 allows a remote attacker who has already compromised the renderer process to break out of the sandbox using a crafted video file. The flaw stems from insufficient validation of untrusted input (CWE-20) and carries a scope-changing CVSS 3.1 score of 9.6, though Google rated the underlying Chromium severity as Low and no public exploit has been identified at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to have ALREADY compromised the Chrome renderer process - this is not a standalone remote bug but the sandbox-escape link of a multi-stage chain. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict and must be weighed carefully. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first compromises a Chrome renderer process via a separate bug (e.g., luring a user to a malicious page), then delivers a specially crafted video file that the Media component mishandles, using the input-validation flaw to escape the sandbox and gain code execution in the browser process context. No public exploit is identified at time of analysis, and success depends on chaining with a prior renderer compromise plus user interaction (UI:R). |
| Remediation | Vendor-released patch: 150.0.7871.47 - upgrade Google Chrome to 150.0.7871.47 or later, which is delivered through Chrome's automatic Stable channel update mechanism (verify via chrome://settings/help and relaunch to apply). … Detailed patch versions, workarounds, and compensating controls in full report. |
