DescriptionCVE.org

Information leak in Core in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to leak sensitive information via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Sensitive information leak in the Core component of Google Chrome prior to version 153.0.8010.36 allows a remote unauthenticated attacker to exfiltrate confidential browser or cross-origin data by inducing a user to visit a crafted HTML page. The CVSS vector rates confidentiality impact as High (C:H), yet Chromium's own internal severity is 'Low,' suggesting the leaked data may be bounded in scope or practical exploitability is constrained by the mandatory user-interaction requirement. …
