Vulnerability

Kinto Attachment's attachments can be replaced on read-only records

Description

Impact

The attachment file of an existing record can be replaced if the user has "read" permission on one of the parent (collection or bucket).

And if the "read" permission is given to "system.Everyone" on one of the parent, then the attachment can be replaced on a record using an anonymous request.

Note that if the parent has no explicit read permission, then the records attachments are safe.

Patches

  • Patch released in kinto-attachment 6.4.0
  • https://github.com/Kinto/kinto-attachment/commit/f4a31484f5925cbc02b59ebd37554538ab826ca1

Workarounds

None if the read permission has to remain granted.
