CVE-2026-34768
Description
A flaw was found in Electron. On Windows, when an application is installed to a path containing spaces and configured to open at login, the executable path is written to the system's Run registry key without proper quoting. An attacker with write access to an ancestor directory can exploit this to cause a different, malicious executable to run at login instead of the intended application, potentially leading to arbitrary code execution. Exploitation typically requires a non-standard installation location.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
