An issue was discovered in SubmitEntityAction in Wikibase in MediaWiki through 1.39.3. Because it doesn't use EditEntity for undo and restore, the intended interaction with AbuseFilter does not occur.
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
