Summary
A vulnerability in electron-updater prior to 26.15.0 allows an empty path component in the LD_LIBRARY_PATH environment variable, adding the current working directory to the dynamic linker search path. An attacker can execute arbitrary code by placing a malicious shared library in the directory from which the AppImage is launched.
Risk Assessment
The organization faces a risk of arbitrary code execution when a vulnerable Electron app is launched from an attacker-controlled directory via AppImage. This could lead to system compromise or data theft.
Recommendation
Immediately update electron-updater to version 26.15.0 or later. Until updated, avoid running AppImage from directories accessible to untrusted users.
Original NVD description (English source)
electron-updater allows for automatic updates for Electron apps. Prior to 26.15.0, AppImage targets built by app-builder-lib could use an empty path component when setting the LD_LIBRARY_PATH environment variable at runtime. This causes the current working directory to be added to the dynamic linker search path, which may allow an attacker to execute arbitrary code by placing a malicious shared library in the directory from which the AppImage is launched. This issue has been fixed in version 26.15.0.
