Inappropriate implementation in CORS in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: Low)
AI Analysis
Technical Summary
This vulnerability involves an inappropriate implementation of Cross-Origin Resource Sharing (CORS) in Google Chrome versions before 151.0.7922.72. An attacker with control over the renderer process can exploit this flaw to leak data from other origins by crafting a malicious HTML page. The vulnerability requires prior compromise of the renderer process, limiting the attack surface. The Chromium project rates this issue as low severity.
Potential Impact
An attacker who has already compromised the renderer process in affected Chrome versions can leak cross-origin data, potentially exposing sensitive information from other web origins. However, the vulnerability does not allow initial compromise or remote code execution by itself. No known active exploitation has been reported.
Mitigation Recommendations
A fix is available in Google Chrome version 151.0.7922.72. Users and administrators should update to this version or later to remediate the vulnerability. Since this is a client-side browser vulnerability, updating the browser is the primary mitigation step.
