CVE-2023-39956: Electronjs Electron

Medium severity, CVSS 6.6. EPSS: 0.5% chance of exploitation in the next 30 days.

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

• Electronjs Electron: before 22.3.9 (fixed in 22.3.9); from 23.0.0, before 23.3.13 (fixed in 23.3.13); from 24.0.0, before 24.7.1 (fixed in 24.7.1); from 25.0.0, before 25.5.0 (fixed in 25.5.0); version 26.0.0 only
