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."}], "lastModified": "2026-09-23T18:30:42.573", "sourceIdentifier": "security-advisories@github.com"}
