The vulnerability requires prior compromise of the renderer process, elevating risk through multi-stage exploits in real-world attack scenarios.
Description
CVE-2026-87618 is a vulnerability in Google Chrome's storage management on Windows systems prior to version 153.0.8010.36. Incorrect reference resolution in the storage module allows an attacker who has already compromised the renderer process to execute arbitrary code outside the Chrome sandbox. This represents a classic sandbox escape and is rated Low severity by Chromium, though the technical impact (code execution outside sandbox) is significant. The vulnerability requires a two-stage attack chain: first renderer compromise via crafted HTML pages, then sandbox escape through this CVE.
