Blinko through 1.8.8 Private Attachment Read via /api/file Route

Blinko through 1.8.8 contains a broken access control vulnerability in the /api/file route that allows authenticated users to read other users' private attachments due to a flawed owner check. Attackers can supply another user's stored filename, following a basename plus millisecond-timestamp pattern, to download private, non-shared attachments.

CVE-2026-85624 Média · 6.5 CWE-639 04/09/2026

Blinko 1.8.7 Cross-User Private Note Disclosure via noteReferenceList

Blinko 1.8.7 contains a cross-user private note disclosure vulnerability in the noteReferenceList procedure that performs no ownership verification on supplied note identifiers. Authenticated attackers can enumerate sequential note IDs and retrieve complete content of other users' private notes including attachments and tags.

CVE-2026-85607 Alta · 8.8 CWE-639 04/09/2026

Blinko 1.8.7 Cross-User AI Conversation Read and Write via message tRPC Router

Blinko 1.8.7 contains an authorization bypass (IDOR) vulnerability in multiple tRPC procedures (message.list, message.update, message.delete, message.clearAfter in server/routerTrpc/message.ts and conversation.clearMessages in server/routerTrpc/conversation.ts). Although these procedures require authentication, they query the database by caller-supplied conversation or message ID without verifying that the resource belongs to the requesting account. Any authenticated user can therefore read another user's full AI chat history, modify individual message content, and delete or wipe entire conversations by enumerating sequential integer IDs.

CVE-2026-23482 Alta · 7.5 Exploit público CWE-22 23/03/2026

Blinko: Unauthorized Arbitrary File Read - /api/file/temp

Blinko is an AI-powered card note-taking project. Prior to version 1.8.4, the file server endpoint does not perform permission checks on the temp/ path and does not filter path traversal sequences, allowing unauthorized attackers to read arbitrary files on the server. When scheduled backup tasks are enabled, attackers can read backup files to obtain all user notes and user TOKENS. This issue has been patched in version 1.8.4.

CVE-2026-23481 Média · 6.5 CWE-22 23/03/2026

CVE-2026-23480 Alta · 8.8 CWE-288 23/03/2026

Blinko: Low Privilege User Privilege Escalation - upsertUser Endpoint

Blinko is an AI-powered card note-taking project. Prior to version 1.8.4, there is a privilege escalation vulnerability. The upsertUser endpoint has 3 issues: it is missing superAdminAuthMiddleware, any logged-in user can call it; the originalPassword is an optional parameter and if not provided password verification is skipped; there is no check for input.id === ctx.id (ownership verification). This could result in any authenticated user modifying other users' passwords, direct escalation to superadmin, and complete account takeover. This issue has been patched in version 1.8.4.
