CVE-2024-1402 (GCVE-0-2024-1402)

Vulnerability from cvelistv5 – Published: 2024-02-09 15:09 – Updated: 2024-08-01 18:40

Title

Denial of service in mattermost mobile apps and server via emoji reactions

Summary

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 and to crash the server due to overloading when clients attempt to retrive the aforementioned post.
