Improper input validation in FindInPage in Google Chrome prior to 152.0.7977.65 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 leakage in Google Chrome's FindInPage component affects all versions prior to 152.0.7977.65. Exploitation requires a remote attacker to have already compromised the renderer process and then deliver a crafted HTML page that triggers improper input validation, exposing data from a different origin accessible in the browser session. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to have already compromised the Chrome renderer process - this is an explicit, stated prerequisite in the CVE description, not an inferred one, and represents a significant independent technical barrier. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is substantially constrained by the compound exploitation prerequisites. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has separately exploited a Chrome renderer vulnerability to gain renderer process control then directs the victim's browser to a crafted HTML page. The page triggers improper input validation in the FindInPage subsystem, causing cross-origin data accessible in the victim's browser session - such as content from another open tab or frame - to leak into the attacker-controlled renderer context. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later, which contains the vendor-released patch. … Detailed patch versions, workarounds, and compensating controls in full report. |
