CVE-2026-9264
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA cross-site scripting (XSS) vulnerability in SketchUp 2026's Dynamic Components feature allows remote code execution and local file exfiltration through maliciously crafted SKP files. The vulnerability stems from improper input sanitization in the component options window, enabling attackers to execute arbitrary system commands and read local files without user interaction by exploiting an embedded Internet Explorer 11 browser.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA critical XSS vulnerability exists in SketchUp 2026's Dynamic Components feature where improper input sanitization in the component options window allows attackers to inject malicious scripts. This is compounded by the application's use of an embedded Internet Explorer 11 browser, which can be leveraged to achieve arbitrary system command execution and local file exfiltration without any user interaction when opening specially crafted SKP files.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm SketchUp 2026 installation and versionCheck installed programs list or run 'sketchup --version' from command line if available; otherwise locate SketchUp.exe in Program Files and check file properties for version infoAffected if SketchUp version is exactly 2026.x or falls within the 2026 release line
-
Verify Dynamic Components extension is loadedLaunch SketchUp, open the Extension Manager (Window > Extension Manager) or check for 'Dynamic Components' toolbar/menu item visible in the UIAffected if Dynamic Components extension shows as enabled or installed
-
Confirm embedded browser component is activeIn SketchUp 2026, check Component Options window (Window > Component Options) for any embedded web content rendering; also check if IEFrame.dll or similar browser DLLs are loaded when Dynamic Components are usedAffected if Embedded browser renders web content within the Dynamic Components interface
-
Review recent SKP file access eventsCheck Windows Event Viewer under Security/Application logs for SketchUp.exe file open events, or manually review recently opened SKP files from SketchUp's recent files listAffected if Any untrusted or externally sourced SKP files were opened recently
-
Detect signs of code execution or file accessUse Process Explorer or Task Manager to look for unexpected child processes spawned by SketchUp.exe (cmd.exe, powershell.exe, or network-aware processes); also check for unauthorized file reads in filesystem audit logsAffected if SketchUp has spawned system commands or accessed files outside normal operation
You are affected if SketchUp 2026 is installed with Dynamic Components enabled, the embedded browser is active, and you have opened any untrusted or externally obtained SKP files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied patches when available; in the interim, disable the Dynamic Components feature or restrict handling of untrusted SKP files, and implement input validation/sanitization within the component options window to neutralize script injection attempts.
