Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Insecure Security Defaults: Historically, the background process explicitly disabled core Electron security boundaries like webSecurity and contextIsolation. This allowed renderer environments to bypass the Same-Origin Policy and expose dangerous internal APIs. Developers must never disable these flags.
Cross-Site Scripting (XSS): RSS feed items parsed using DOMParser were rendered without adequate sanitization. In an Electron context with relaxed security flags, this could directly escalate to Remote Code Execution (RCE).
