Incorrect authorization in Media in Google Chrome on on Windows prior to 152.0.7977.65 allowed a remote attacker who had compromised the renderer process to bypass system access restrictions via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Incorrect authorization in Google Chrome's Media component on Windows enables a remote attacker who has already compromised the renderer process to bypass OS-level system access restrictions via a crafted HTML page. Affected are all Chrome versions prior to 152.0.7977.65 on Windows. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two chained conditions: (1) the attacker must already have achieved code execution within Chrome's renderer process via a separate, unrelated vulnerability - this is a non-trivial prerequisite that substantially limits the exploitable population; (2) the victim must be running Chrome on Windows (not macOS, Linux, Android, or iOS), specifically a version prior to 152.0.7977.65. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N) warrants scrutiny. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page that first exploits a separate renderer vulnerability to gain code execution within Chrome's sandboxed renderer process on a Windows host; once inside the renderer, the attacker leverages this Media authorization bypass to issue privileged calls that cross the sandbox boundary and access Windows system resources. No public proof-of-concept code has been identified at time of analysis, but the two-stage chain is a well-understood class of browser exploitation. |
| Remediation | Vendor-released patch: Chrome 152.0.7977.65. … Detailed patch versions, workarounds, and compensating controls in full report. |
