CVE-2026-49450 | BDVDB-2026-377304 Detail

laurent22joplin

Description#

Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.2, Joplin Desktop for Windows omits publisherName from packages/app-desktop/package.json, so the generated app-update.yml causes NsisUpdater.verifySignature() to skip comparison of a downloaded update's Authenticode signer with Joplin's signer. An attacker who controls the update delivery path can replace the update metadata and installer, and the client accepts an installer signed by another publisher or left unsigned after the user approves installation. Successful exploitation runs attacker-controlled code with the user's privileges and can compromise notes, credentials, and local data. This issue is fixed in version 3.7.2.
