CVE-2026-33067
SiYuan has Stored XSS to RCE via Unsanitized Bazaar Package Metadata
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD. Niedriger laut GHSA (mittel).
Beschreibung
SiYuan is a personal knowledge management system. Versions 3.6.0 and below render package metadata fields (displayName, description) using template literals without HTML escaping. A malicious package author can inject arbitrary HTML/JavaScript into these fields, which executes automatically when any user browses the Bazaar page. Because SiYuan's Electron configuration enables nodeIntegration: true with contextIsolation: false, this XSS escalates directly to full Remote Code Execution on the victim's operating system — with zero user interaction beyond opening the marketplace tab. This issue has been fixed in version 3.6.1.
