Trilium Notes is a cross-platform, hierarchical note taking application focused on building large personal knowledge bases. Prior to 0.102.2, a malicious ZIP archive imported with safe import enabled achieves RCE via #docName path traversal and XSS by combining a payload note (type: code, mime: text/plain) containing raw HTML/JS and a trigger note (type: doc or type: launcher) with a #docName label that uses ../ path traversal to point at the payload note's API endpoint. The desktop client Electron renderer runs with nodeIntegration enabled, so an RCE is triggered once the payload is executed. This vulnerability is fixed in 0.102.2.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
