Summary
Electron Packager bundles Electron-based application source code with a renamed Electron executable and supporting files into folders ready for distribution. A random segment of ~1-10kb of Node.js heap memory allocated either side of a known buffer will be leaked into the final executable. This memory _could_ contain sensitive information such as environment variables, secrets files, etc. This issue is patched in 18.3.1.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of electron/packager published their own advisory on GitHub. Reviewed sources take precedence over it.
