Incomplete cleanup in GetUserMedia in Google Chrome prior to 153.0.8010.47 allowed a remote attacker who had compromised the renderer process and leveraged social engineering to obtain cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data disclosure in Google Chrome versions prior to 153.0.8010.47 occurs when an attacker who has already compromised the renderer process lures a victim to a crafted HTML page. The weakness lives in the GetUserMedia media-capture code path, where incomplete cleanup (CWE-459) leaves cross-origin data recoverable, as captured by the CVSS v3.1 vector AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N (score 3.1) - unauthenticated network reach but high attack complexity, mandatory user interaction, and confidentiality-only, low-magnitude impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a multi-condition chain: (1) the attacker must have already compromised the Chrome renderer process through a separate vulnerability, (2) the victim must be driven via social engineering to a crafted HTML page, and (3) user interaction is required (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely low-priority issue despite being a Chrome vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade Google Chrome to 153.0.8010.47 or later, distributed through the Chrome Releases stable channel update (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0541751186.html) and via chrome://settings/help; enterprise fleets should force the upgrade and verify the reported version rather than relying on auto-update alone. … Detailed patch versions, workarounds, and compensating controls in full report. |
