CVE-2026-30230 (GCVE-0-2026-30230)

Vulnerability from cvelistv5 – Published: 2026-03-06 21:09 – Updated: 2026-03-09 20:54

Title
Flare: Password‑Protected Thumbnail Bypass
Summary
Flare is a Next.js-based, self-hostable file sharing platform that integrates with screenshot tools. Prior to version 1.7.2, the thumbnail endpoint does not validate the password for password‑protected files. It checks ownership/admin for private files but skips password verification, allowing thumbnail access without the password. This issue has been patched in version 1.7.2.
Severity
8.2 (High)

Title
Flare: Private File IDOR via raw/direct endpoints
Summary
Flare is a Next.js-based, self-hostable file sharing platform that integrates with screenshot tools. Prior to version 1.7.2, the raw and direct file routes only block unauthenticated users from accessing private files. Any authenticated, non‑owner user who knows the file URL can retrieve the content, which is inconsistent with stricter checks used by other endpoints. This issue has been patched in version 1.7.2.

Title
Wekan has Cross-Board IDOR in Custom Fields Update Endpoints
Summary
Wekan is an open source kanban tool built with Meteor. Versions 8.32 and 8.33 have a critical Insecure Direct Object Reference (IDOR) issue which could allow unauthorized users to modify custom fields across boards through its custom fields update endpoints, potentially leading to unauthorized data manipulation. The PUT /api/boards/:boardId/custom-fields/:customFieldId endpoint in Wekan validates that the authenticated user has access to the specified boardId, but the subsequent database update uses only the custom field's _id as a filter without confirming the field actually belongs to that board. This means an attacker who owns any board can modify custom fields on any other board by supplying a foreign custom field ID, and the same flaw exists in the POST, PUT, and DELETE endpoints for dropdown items under custom fields. The required custom field IDs can be obtained by exporting a board (which only needs read access), since the exported JSON includes the IDs of all board components. The authorization check is performed against the wrong resource, allowing cross-board custom field manipulation. This issue has been fixed in version 8.34.
