Information leak in Scroll in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data exposure in Google Chrome's Scroll component (all versions prior to 153.0.8010.36) enables an attacker who has already achieved renderer process compromise to exfiltrate sensitive data from other web origins via a crafted HTML page. This is a secondary-stage vulnerability - it does not provide initial access but extends an existing renderer compromise into a cross-origin information leak. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation has two hard prerequisites: first, the attacker must have already compromised the Chrome renderer process via a separate, independent vulnerability - this is not a standalone exploit and provides no initial access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is moderate in the context of a chained attack but negligible as a standalone vector. … 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 | Update Google Chrome to version 153.0.8010.36 or later using Chrome's built-in update mechanism (chrome://settings/help) or by downloading from the official Chrome stable channel advisory at chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
