Joplin: Logic error in Joplin Server allows a signed-in user to read any note from its internal server ID

CVSS 3.1 6.5 MEDIUMCheck source for fixed versionsKEV status unknown

cve-program · CVE-2026-55179

Published

Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.2, Joplin Server's GET /items/:id/content route in packages/server/src/routes/index/items.ts loads item content from an attacker-supplied internal server ID without checking whether the signed-in user owns or can access that item. Any authenticated user who obtains or guesses another user's item ID can read the corresponding note or item content when end-to-end encryption does not protect it. This issue is fixed in version 3.7.2.
