Deeper analysis

CVE-2025-8880 is a race condition vulnerability (CWE-362) in the V8 JavaScript engine within Google Chrome versions prior to 139.0.7258.127. Published on 2025-08-13, it allows a remote attacker to execute arbitrary code inside the browser's sandbox via a crafted HTML page. Chromium security has rated it as High severity with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

A remote attacker can exploit this vulnerability by tricking a user into visiting a malicious website or interacting with a crafted HTML page, requiring no privileges but relying on user interaction. Successful exploitation grants arbitrary code execution confined to the sandbox, with high impacts on confidentiality, integrity, and availability.

Mitigation is available via the Google Chrome stable channel update to version 139.0.7258.127 or later, as announced in the Chrome Releases blog post at https://chromereleases.googleblog.com/2025/08/stable-channel-update-for-desktop_12.html and detailed in the Chromium issue tracker at https://issues.chromium.org/issues/433533359. Security practitioners should prioritize updating affected Chrome installations.
