Summary

CVE-2025-10891 is a high-severity External Control of Assumed-Immutable Web Parameter (CWE-472) vulnerability in Google Chrome. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2025-10891 is an integer overflow vulnerability (CWE-472) in the V8 JavaScript and WebAssembly engine within Google Chrome versions prior to 140.0.7339.207. The flaw allows a remote attacker to potentially trigger heap corruption by processing a crafted HTML page, as reported with a Chromium security severity rating of High and 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 convincing a user to visit a malicious website or interact with a specially crafted HTML page, requiring no privileges but relying on user interaction. Successful exploitation could lead to arbitrary code execution, including potential remote code execution with the renderer process privileges, enabling high-impact confidentiality, integrity, and availability violations such as data theft, sandbox escape precursors, or full compromise of the affected browser instance.

Mitigation is addressed in the Google Chrome Stable Channel update announced on the Chrome Releases blog (https://chromereleases.googleblog.com/2025/09/stable-channel-update-for-desktop_23.html), which patches the issue in version 140.0.7339.207 and later. Additional details are available in the Chromium issue tracker (https://issues.chromium.org/issues/443765373). Security practitioners should prioritize updating affected Chrome installations and advise users to enable automatic updates.

prevents

Secure coding standards require server-side verification of client-supplied data, eliminating the root cause of external control of immutable parameters.

finds

Security testing in development and acceptance will detect parameter tampering vulnerabilities before deployment.

prevents

Secure development lifecycle mandates input validation and integrity checks that directly prevent external tampering of assumed-immutable parameters.

prevents

Application security requirements explicitly call for validation of all inputs, including hidden fields, mitigating CWE-472.

none

Information access restriction can limit which parameters users may influence, providing a secondary layer of defense.
