The Electron framework lets users write cross-platform desktop applications using JavaScript, HTML and CSS. In versions of Electron IPC prior to 9.4.0, 10.2.0, 11.1.0, and 12.0.0-beta.9, messages sent from the main process to a subframe in the renderer process, through webContents.sendToFrame, event.reply or when using the remote module, can in some cases be delivered to the wrong frame. If your app uses remote, calls webContents.sendToFrame, or calls event.reply in an IPC message handler then it is impacted by this issue. This has been fixed in versions 9.4.0, 10.2.0, 11.1.0, and 12.0.0-beta.9. There are no known workarounds for this issue.
CVE-2020-26272
This medium-severity CVE scores 5.4 under NVD CVSS v3. EPSS exploit probability: 1.7%, top 25% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
