CVE-2026-114606 jgraph CVE debrief

Who should care

Security teams responsible for Electron-based applications, developers using similar IPC mechanisms, and administrators managing draw.io Desktop installations should review and update draw.io Desktop to version 31.4.4 or later, assess exposure of Electron-based applications using similar IPC mechanisms, and implement additional security controls for file access and validation. The vulnerability allows arbitrary local-file disclosure in draw.io Desktop, and

Why it matters

CVE-2026-114606 allows arbitrary local-file disclosure in draw.io Desktop, impacting Electron-based applications and requiring additional security controls

• Potential unauthorized access to sensitive local files
• Increased risk of data breaches or exposure
• Need for additional security controls and validation
• Potential impact on Electron-based applications using similar IPC mechanisms

Technical summary

draw.io Desktop prior to version 31.4.4 is vulnerable to arbitrary local-file disclosure through Electron main process's read-side IPC handlers, allowing any frame executing in the app's file:// origin to read the contents of local files that the same origin is explicitly forbidden to write. The vulnerability is caused by a read/write authorization asymmetry, where the read side is not protected by assertWritablePath. This issue is fixed in version 31.4.4. Security teams should review and update draw.io Desktop to version 31.4.4 or later, assess exposure of Electron-based applications using similar IPC mechanisms, and implement additional security controls for file access and validation.

Defensive priority

Medium priority for Electron-based application security assessments

Recommended defensive actions

• Review and update draw.io Desktop to version 31.4.4 or later
• Assess exposure of Electron-based applications using similar IPC mechanisms
• Implement additional security controls for file access and validation
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
