CVE-2024-1314
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. Updating to 6.4.0 or applying the patch individually (if updating is not feasible) is strongly recommended. ### References - https://bugzilla.mozilla.org/show_bug.cgi?id=1879034
