What is CVE-2026-41572?
CVE-2026-41572 is a medium-severity missing authorization vulnerability in enchant97 note-mark, published on 4 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Note Mark is an open-source note-taking application. Prior to version 0.19.3, after a note-mark owner soft-deletes a public book, its notes and uploaded assets stay readable at /api/notes/{id}, /api/notes/{id}/content, the slug URL, and the asset endpoints. Unauthenticated callers who hold the note ID or the slug path retain access. GORM's soft-delete scope does not reach the raw "JOIN books ..." clauses used by the note and asset queries. This issue has been patched in version 0.19.3.
Weakness: CWE-285
