CVE-2026-14089: Insufficient validation of untrusted input in Google Chrome
CVE-2026-14089 is a vulnerability in Google Chrome's PopupBlocker component prior to version 150.0.7871.47. It involves insufficient validation of untrusted input, which allows a remote attacker who has compromised the renderer process to perform UI spoofing via a crafted HTML page. The issue is classified with low severity by Chromium security. There is no explicit CVSS score or detailed vendor remediation level provided in the available data.
AI Analysis
Technical Summary
This vulnerability arises from insufficient validation of untrusted input in the PopupBlocker feature of Google Chrome before version 150.0.7871.47. An attacker with control over the renderer process can exploit this flaw to conduct UI spoofing attacks by crafting malicious HTML content. The vulnerability is acknowledged by Chromium security with a low severity rating. The vendor advisory linked does not explicitly state the availability of a patch or remediation details, but the affected version is prior to 150.0.7871.47, implying that updating to this version or later likely addresses the issue.
Potential Impact
The impact is limited to UI spoofing, which can mislead users by displaying deceptive user interface elements. This could potentially facilitate phishing or social engineering attacks if an attacker has already compromised the renderer process. There is no indication of code execution or privilege escalation solely from this vulnerability. No known exploits are reported in the wild.
Mitigation Recommendations
The vendor advisory does not explicitly confirm a patch or remediation level. However, the vulnerability affects versions prior to 150.0.7871.47, indicating that updating Google Chrome to version 150.0.7871.47 or later is the recommended mitigation. Users should apply this update once available. Patch status is not yet confirmed explicitly; therefore, check the vendor advisory for the latest remediation guidance.
