Technical ContextAI · show details
This vulnerability is classified as Code Injection (CWE-94), which allows attackers to inject and execute arbitrary code within the application. Electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS. Electron apps that are launched as command line executables are impacted. Specifically this issue can only be exploited if the following conditions are met: 1. The app is launched with an attacker-controlled working directory and 2. The attacker has the ability to write files to that working directory. This makes the risk quite low, in fact normally issues of this kind are considered outside of our threat model as similar to Chromium we exclude Physically Local Attacks but given the ability for this issue to bypass certain protections like ASAR Integrity it is being treated with higher importance. This issue has been fixed in versions:26.0.0-beta.13, 25.4.1, 24.7.1, 23.3.13, and 22.3.19. There are no app side workarounds, users must update to a patched version of Electron. Affected products include: Electronjs Electron.

Attack Technique
Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
