CVE-2026-54672
Description
A flaw was found in electron-updater, a component used for automatic updates in Electron applications. This vulnerability arises because AppImage targets, built by app-builder-lib, incorrectly add the current working directory to the dynamic linker search path when setting the LD_LIBRARY_PATH environment variable. An attacker could exploit this by placing a malicious program in the same directory as an AppImage, which would then be executed when the AppImage is launched. This could allow the attacker to run arbitrary code on the affected system.
Statement
The vulnerability in electron-builder's AppImage packaging only affects applications distributed as AppImage format, where an empty LD_LIBRARY_PATH component causes the current working directory to be added to the dynamic linker search path. Red Hat products that bundle electron-builder components are not affected: the goose RPM is distributed as an RPM package (not AppImage), and Podman Desktop uses Flatpak and tar.gz targets on Linux (AppImage is not configured in its electron-builder config). The vulnerable AppImage code path is never exercised in any Red Hat product.
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.
