CyberRota Analysis
AI-GeneratedElectron applications using custom protocol handlers are vulnerable to session isolation issues, where cached responses may be reused across different session partitions if the ProtocolResponse does not specify a session. This could lead to unintended data exposure between isolated contexts. Developers of affected applications should prioritize updating to the fixed versions to mitigate potential risks to user privacy and data security.

Original NVD Description
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 40.10.6, 41.9.1, 42.5.1, and 43.0.0, when a custom protocol handler returned a ProtocolResponse with a url and no session, Electron made the upstream request through defaultSession instead of the session that handled the protocol. A cached response could then be reused across otherwise isolated session partitions. Apps that use ProtocolResponse.url, omit ProtocolResponse.session, and rely on separate sessions to isolate content are affected. This issue is fixed in versions 40.10.6, 41.9.1, 42.5.1, and 43.0.0.
