Electron is a widely used cross-platform app framework; this flaw lets untrusted webview content gain Node-enabled workers, risking code execution across many desktop apps.
CVE-2026-102676
Webview can create Node-enabled Web Workers despite nodeIntegration disabled.
Is CVE-2026-102676 being exploited?
Not confirmed. CVE-2026-102676 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked.
How severe is CVE-2026-102676?
CVE-2026-102676 is rated High with a CVSS score of 8.3. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Untrusted <webview> content can spawn Node-enabled Web Workers, enabling privilege escalation and potential code execution in Electron apps.
Patch when possible
- affected< 41.10.6
- affected>= 42.0.0-alpha.1 and < 42.9.2
- affected>= 43.0.0-alpha.1 and < 43.4.1
- affected>= 44.0.0-alpha.1 and < 44.0.0-beta.5
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
