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.\n\n## Affected\n\n- `joplin < 3.7.13`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":47,"depthScoreParts":{"impact":46.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
