Original summary
Normalized public record · Updated Oct 23, 2026
Electron context isolation bypass via nested unserializable return value
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
Apps using `contextIsolation` and `contextBridge` are affected.
Potential impact
Apps using contextIsolation and contextBridge are affected. This is a context isolation bypass, meaning that code running in the main world context in the renderer can reach into the isolated Electron context and perform privileged actions.

| Consult the referenced vendor advisory for affected versions. | Consult source advisory |
Matching a version is only one part of assessing exposure. QFinch has not assessed your environment on this public page.
Remediation
Apply the vendor-supported fixed release or mitigation, then verify the affected component is no longer reachable.
- Confirm the affected product and reachable code path exist in your environment.
- Apply the vendor-supported patch or mitigation from the primary advisory.
- Rescan the exact deployed revision and retain verification evidence.
