  - Mattermost fails to check if a custom emoji reaction exists when sending it to a post and to limit the
    amount of custom emojis allowed to be added in a post, allowing an attacker sending a huge amount of non-
    existent custom emojis in a post to crash the mobile app of a user seeing the post. (CVE-2024-1402)
