Insufficient validation of untrusted input in Dawn in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-17867 affects the Dawn component in Google Chrome versions before 151.0.7922.72. It stems from insufficient validation of untrusted input, which may enable a remote attacker to perform a sandbox escape through a crafted HTML page. The sandbox escape could allow code execution outside the intended restricted environment, increasing the risk of system compromise. The vulnerability is classified under CWE-20 (Improper Input Validation). No CVSS score or patch details are available in the provided data.
Potential Impact
If exploited, this vulnerability could allow a remote attacker to bypass Chrome's sandbox protections, potentially leading to execution of arbitrary code with elevated privileges outside the browser sandbox. This could compromise the security boundaries designed to isolate web content from the underlying system. However, no known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor official Google Chrome security advisories for updates and apply the official fix once available. Until a patch is confirmed, cautious browsing and avoiding untrusted HTML content may reduce risk.
