CVE-2026-13789 is a use-after-free vulnerability in the GPU subsystem of Google Chrome versions before 150.0.7871.47. Exploitation requires prior compromise of the renderer process and could lead to sandbox escape via a crafted HTML page. The vulnerability was publicly disclosed with a high severity rating by Chromium security. Although a vendor advisory link is provided, it does not explicitly state the availability of a patch or mitigation steps. The affected product is Google Chrome, and the vulnerability is not related to a cloud service.

If exploited, this vulnerability could allow an attacker with control over the renderer process to escape the Chrome sandbox, potentially leading to execution of code outside the restricted environment. This elevates the risk of further system compromise beyond the browser sandbox. No known exploits in the wild have been reported at this time.
