- Summary
- Docmost has cross-page attachment overwrite via flawed attachmentId overwrite validation
- Details
-
Docmost is open-source collaborative wiki and documentation software. Starting in version 0.3.0 and prior to version 0.71.0, improper authorization in Docmost allows a low-privileged authenticated user to overwrite another page's attachment within the same workspace by supplying a victim
attachmentIdtoPOST /api/files/upload. This is a remote integrity issue requiring no victim interaction. Version 0.71.0 contains a patch. - Database specific
