- Affected
- PyPI kinto-attachment <= 6.3.2
- Fixed in
- 6.4.0· Vendor fix available
- Issue
- 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/showbug.cgi?id=1879034
Recommended action: Upgrade to 6.4.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
