 - Mattermost fails to limit the amount of data extracted from compressed archives during board import in
   Mattermost Boards allowing an attacker to consume excessive resources, possibly leading to Denial of
   Service, by importing a board using a specially crafted zip (zip bomb). (CVE-2023-48268) (MMSA-2023-00218)

 - Mattermost fails to properly limit the characters allowed in different fields of a block in Mattermost
   Boards allowing a attacker to consume excessive resources, possibly leading to Denial of Service, by
   patching the field of a block using a specially crafted string. (CVE-2023-40709) (MMSA-2023-00219)

 - Mattermost fails to properly check a redirect URL parameter allowing for an open redirect was possible
   when the user clicked 'Back to Mattermost' after providing a invalid custom url scheme in
   /oauth/{service}/mobile_login?redirect_to= (CVE-2023-47168) (MMSA-2023-00252)
