AnalysisAI

Server-side request forgery in opengeos GeoLibre up to version 2.3.0 allows malicious plugins or attacker-controlled WebView content to invoke the application's native Tauri IPC commands (fetch_url_bytes, resolve_url_redirect) to issue HTTP requests from the desktop process's privileged network position, bypassing browser CORS restrictions and potentially reaching cloud instance-metadata services (169.254.169.254) inaccessible to ordinary browser fetch. The vulnerability is fixed in GeoLibre 2.4.0 via commit b745f62e29fa37364686525a21eee5e5c0f8a369. …
