CVE-2026-13942: Insufficient validation of untrusted input in Google Chrome
Inappropriate implementation in Video Capture in Google Chrome on ChromeOS prior to 150.0.7871.47 allowed a local attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)
AI Analysis
Technical Summary
This vulnerability arises from improper input validation in the Video Capture feature of Google Chrome on ChromeOS versions before 150.0.7871.47. It enables a local attacker to craft an HTML page that can spoof the user interface, potentially misleading users. The CVSS vector indicates low attack complexity and no privileges required, but user interaction is necessary. Confidentiality and availability impacts are not present; the impact is limited to integrity via UI spoofing. The vendor advisory is available but does not explicitly state patch or fix details, so patch status is not confirmed.
Potential Impact
The impact is limited to UI spoofing, which can mislead users into believing they are interacting with legitimate browser UI elements. There is no direct confidentiality or availability impact. The attack requires local access and user interaction. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed—check the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html for current remediation guidance. Until official fixes are confirmed, users should exercise caution with untrusted local content that could exploit this vulnerability.
