This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.6%, top 56% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Joplin is a free, open source note taking and to-do application, which can handle a large number of notes organised into notebooks. Prior to version 3.3.3, path traversal is possible in Joplin Server if static file path starts with css/pluginAssets or js/pluginAssets. The findLocalFile function in the default route calls localFileFromUrl to check for special pluginAssets paths. If the function returns a path, the result is returned directly, without checking for path traversal. The vulnerability allows attackers to read files outside the intended directories. This issue has been patched in version 3.3.3.
