CyberRota Analysis
AI-GeneratedTrilium, an open-source hierarchical note-taking application, is vulnerable in versions prior to 0.104.0 due to its automatic image-download feature, which improperly handles file:// URLs, allowing authenticated users to access arbitrary local files and potentially crash the server. This flaw can lead to sensitive data exposure, such as reading system files like /etc/passwd, and can also result in denial-of-service conditions through uncontrolled memory allocation. Organizations using affected versions should prioritize updating to 0.104.0 to mitigate these risks.

Original NVD Description
Trilium is an open-source hierarchical note-taking application. In versions prior to 0.104.0, the automatic image-download feature accepts file:// URLs in a note's img tags and reads the referenced local file with no path validation, allowing any authenticated user to disclose arbitrary files readable by the Trilium process. When a text note is saved, Trilium scans its HTML for image sources and downloads each external one; because the HTML sanitizer keeps file as an allowed scheme, a source such as file:///etc/passwd is passed straight to a filesystem read and its contents are stored as a note attachment the user can then retrieve. Pointing the same primitive at an unbounded source such as /dev/zero causes uncontrolled memory allocation that crashes the server process. The feature is enabled by default and is reachable through the web UI, the ETAPI, the web clipper, and note imports, requiring only an authenticated session or an ETAPI token. This issue is fixed in version 0.104.0
