CVE-2026-35613
Path traversal in coursevault-preview due to improper base-directory boundary validation
Description
coursevault-preview is a utility for previewing course material files from a configured directory. coursevault-preview versions prior to 0.1.1 contain a path traversal vulnerability in the resolveSafe utility. The boundary check used String.prototype.startsWith(baseDir) on a normalized path, which does not enforce a directory boundary. An attacker who controls the relativePath argument to affected CoursevaultPreview methods may be able to read files outside the configured baseDir when a sibling directory exists whose name shares the same string prefix. This vulnerability is fixed in 0.1.1.
