Last modified
CVE-2025-35965 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Mattermost versions 10.4.x <= 10.4.2, 10.5.x <= 10.5.0, 9.11.x <= 9.11.10 fail to validate the uniqueness and quantity of task actions within the UpdateRunTaskActions GraphQL operation, which allows an attacker to create task items containing an excessive number of actions triggered by specific posts, overloading the server and leading to a denial-of-service (DoS) condition.. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
