How to Fix CVE-2024-46993

To remediate this vulnerability, upgrade all affected Electron dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

electron fixed: 28.3.2 
npm install electron@28.3.2
electron fixed: 29.3.3 
npm install electron@29.3.3
electron fixed: 30.0.3 
npm install electron@30.0.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls electron

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-46993, inspect your project dependencies using npm:

npm ls electron

Analyze the terminal output to locate any version of Electron in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 28.3.2), your application is affected.

Note: The npm ls electron command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-122: Heap-based Buffer Overflow, where a heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). In Electron, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The `nativeImage.createFromPath()` and `nativeImage.createFromBuffer()` functions call a function downstream that is vulnerable to a heap buffer overflow. An Electron program that uses either of the affected functions is vulnerable to a buffer overflow if an attacker is in control of the image's height, width, and contents. ### Workaround There are no app-side workarounds for this issue. You must update your Electron version to be protected. ### Patches - `v28.3.2` - `v29.3.3` - `v30.0.3` ### For More Information If you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org).
