CVE-2026-54672: CWE-427: Uncontrolled Search Path Element in electron-userland electron-builder
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.
AI Analysis
Technical Summary
The electron-updater component of electron-builder versions before 26.15.0 has a CWE-427 vulnerability where an empty path component in the LD_LIBRARY_PATH environment variable causes the current working directory to be added to the dynamic linker search path. This can be exploited by an attacker who places a malicious shared library in the directory from which the AppImage is launched, potentially leading to arbitrary code execution. The vulnerability affects AppImage targets built by app-builder-lib and has a CVSS 3.1 score of 7.8 (high severity). The issue is resolved in electron-builder version 26.15.0.
Potential Impact
An attacker with the ability to place a malicious shared library in the directory where the AppImage is launched can execute arbitrary code due to the dynamic linker loading libraries from the current working directory. This compromises confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Upgrade electron-builder to version 26.15.0 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is indicated in the available data.
