AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Local malicious-file vector (AV:L) needing no prior privileges (PR:N) but victim interaction (UI:R); successful privilege escalation yields full high C/I/A on the host.

Insufficient validation of untrusted input in Chromoting in Google Chrome on Windows prior to 150.0.7871.47 allowed a local attacker to perform privilege escalation via a malicious file. (Chromium security severity: Low)
AnalysisAI
Local privilege escalation in Google Chrome's Chromoting (Chrome Remote Desktop) component on Windows before 150.0.7871.47 allows a local attacker who plants a malicious file to elevate privileges after the victim interacts with it. The flaw stems from insufficient validation of untrusted input (CWE-20) and carries a 7.8 CVSS but was rated Low severity by Chromium's own team. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the Windows host and that the Chromoting (Chrome Remote Desktop) functionality of Google Chrome be present/active, plus user interaction (UI:R) - the victim must open or otherwise interact with the attacker-supplied malicious file for the escalation to trigger. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are internally consistent and point to a real but bounded risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A low-privileged user (or malware already running as a standard user) on a shared Windows machine drops a specially crafted file where the Chromoting component will process it, then induces the logged-in victim to open or trigger it. Because the file's input is not properly validated, processing occurs in an elevated context and the attacker gains higher privileges. … |
| Remediation | Vendor-released patch: Google Chrome 150.0.7871.47 for Windows - upgrade to this version or later, which Chrome typically applies automatically on restart, so ensuring the browser is fully closed and relaunched is the primary fix (see https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify Windows systems running Chrome before version 150.0.7871.47 with Chrome Remote Desktop enabled; notify relevant teams. …
