The manipulation of the argument id with an unknown input leads to a improper authentication vulnerability. Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.13, packages/server/src/models/ApplicationModel.ts accepts a caller-chosen application authorization identifier, applications/:id/confirm binds that identifier to a logged-in user through a generic consent page, and the public packages/server/src/routes/api/application_auth.ts endpoint passes it to ApplicationModel.createAppPassword without authenticating or binding the redeemer. An attacker can cause a victim to approve the attacker's identifier, redeem a durable application ID and password, and exchange the credential for a victim session with full read and write access to synchronized data. This vulnerability is fixed in 3.7.13.
