AI Analysis
Technical Summary
CVE-2026-13990 is a vulnerability in Google Chrome on Windows platforms before version 150.0.7871.47. It involves insufficient validation of untrusted input within the DataTransfer API, which can be exploited by an attacker who has already compromised the renderer process to conduct UI spoofing attacks through crafted HTML content. This vulnerability does not impact confidentiality or availability but can affect integrity by misleading users via spoofed user interfaces. The CVSS vector indicates the attack requires no privileges but does require user interaction.
Potential Impact
The vulnerability allows an attacker with control over the renderer process to perform UI spoofing, potentially misleading users into interacting with deceptive interfaces. There is no direct impact on confidentiality or availability. The medium severity rating and CVSS score of 6.5 reflect the moderate risk posed by this issue.
Mitigation Recommendations
A fixed version of Google Chrome is available at 150.0.7871.47. Users and administrators should update to this version or later to remediate the vulnerability.
