What it is

Inbox Zero is an AI personal assistant for email. Prior to 2.29.3, the cleaner email stream endpoint used a shared Redis subscription listener, which could deliver thread events for one authenticated account to another authenticated account using the cleaner feature at the same time. This vulnerability is fixed in 2.29.3.
