CVE-2026-44523
CriticalSummary
The Note Mark application prior to version 0.19.4 does not enforce minimum length or entropy for the JWT_SECRET configuration value. It allows any base64-decodable secret, including secrets as short as 1 byte.
Risk Assessment
The lack of proper length and entropy requirements for the secret can lead to easy compromise of security, posing a risk of unauthorized access to user data.
Recommendation
It is recommended to update the application to version 0.19.4 or later to ensure proper security for the JWT_SECRET value.
Other vulnerabilities in Note Mark
See all- CVE-2026-50553High
Note Mark prior to version 0.19.5 improperly validates slug values because the OpenAPI/huma pattern is not anchored, allowing paths with ../ segments to be accepted. Data export commands use these slugs to create files outside the export directory, potentially leading to file writes with root privileges.
- CVE-2026-50554Medium
Note Mark is an open-source note-taking application. Prior to version 0.19.5, GET /api/books/{bookID}/notes is an unauthenticated endpoint that accepts a "deleted" query parameter. When the request is ?deleted=true, the service runs the query with Unscoped() (bypassing GORM's soft-delete scope) but keeps the read-authorization clause as "owner_id = ? OR is_public = ?". As a result, any unauthenticated caller can enumerate the metadata of soft-deleted ("trashed") notes belonging to any public book — notes the owner explicitly deleted and expected to be removed from public view.
Original NVD description (English source)
Note Mark is an open-source note-taking application. Prior to 0.19.4, no minimum length or entropy is enforced on the JWT_SECRET configuration value. The application accepts any base64-decodable secret regardless of size, including secrets as short as 1 byte. This vulnerability is fixed in 0.19.4.
