Impact

Incorrect authorization in Chrome’s WebProtect component for versions prior to 156.0.8078.47 allows a remote attacker to bypass system access restrictions through a crafted HTML page. The flaw is an access‑control weakness (CWE-863) that can elevate privileges within Chrome’s sandboxed environment.

Affected Systems

Google Chrome versions prior to 156.0.8078.47 are affected. Users of older stable releases are at risk until they upgrade to the patched version.

Risk and Exploitability

The CVSS score of 8.8 classifies this as a high‑severity flaw, and the known exploit path requires a malicious web page; the EPSS score is < 1% and it is not currently listed in CISA's KEV catalog. Based on the description, it is inferred that the likely attack vector is a remote attacker hosting a malicious webpage or a compromised site that delivers the crafted page.
