AI Analysis

Impact

The vulnerability is an incorrect authorization check in Chrome Mobile for iOS, which allows a remote attacker to use a crafted HTML page and social engineering to bypass the browser’s system access restrictions. This can enable the attacker to gain unauthorized access to device resources that are normally protected by the browser. The flaw involves a logical error in permission enforcement that is mapped to CWE‑863.

Affected Systems

Google Chrome for iOS versions earlier than 155.0.8059.39 are affected.

Risk and Exploitability

The CVSS score of 6.1 indicates medium severity. The EPSS score of less than 1% shows low likelihood of exploitation, and the issue is not listed in the CISA KEV catalog. The attack vector is remote, utilizing a malicious web page; the required condition for exploitation is a user visiting or interacting with the crafted HTML content. Because the flaw involves only an authorization bypass, it does not lead to arbitrary code execution, but it does expose the device to unauthorized system resource access.
