-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Versions: up to 2.1.0
a vulnerability in Swift enforcement of metadata contraints. By adding metadata in several separate calls, an authenticated attacker can bypass the max_meta_count constraint, potentially resulting in the storage of more metadata than allowed in configuration.
https://launchpad.net/bugs/1365350
If we pass more than 90 metadata in one request, it fails. But if we pass 50 in one request and 50 in another request, the request is successfully processed which is against documentation.
The above case occurs in account and container only. While in object case, the metadata is overwritten with new request's metadata.
