The vulnerability was disclosed in August 2023 and affects Google Chrome browsers before the patched version. This high-severity security flaw could allow a remote attacker to potentially exploit heap corruption through a specially crafted HTML page (Chrome Release, NVD).

The vulnerability is classified as a Use-after-free (CWE-416) issue specifically affecting the Cast functionality in Chrome. It received a CVSS v3.1 base score of 8.8 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating that it can be exploited remotely with low attack complexity, requires user interaction, and could lead to high impacts on confidentiality, integrity, and availability (NVD).

If successfully exploited, the vulnerability could allow an attacker to potentially execute arbitrary code through heap corruption, leading to system compromise. The high CVSS score indicates serious potential consequences including unauthorized information disclosure, data manipulation, or service disruption (NVD).

Google has addressed this vulnerability in Chrome version 115.0.5790.170. Users and administrators should immediately update to this version or later to mitigate the risk.
