CVE-2026-23488

Blinko is an AI-powered card note-taking project. Prior to version 1.8.4, the /api/v1/comment/create endpoint has an unauthorized access vulnerability, allowing attackers to post comments on any note (including private notes) without authorization, even if the note has not been publicly shared. The /api/v1/comment/list endpoint has the same issue, allowing unauthorized viewing of comments on all notes. This issue has been patched in version 1.8.4.
