CVE-2025-41395 Details
Description
Mattermost versions 10.4.x <= 10.4.2, 10.5.x <= 10.5.0, 9.11.x <= 9.11.10 fail to properly validate the props used by the RetrospectivePost custom post type in the Playbooks plugin, which allows an attacker to create a specially crafted post with maliciously crafted props and cause a denial of service (DoS) of the web app for all users.
A denial-of-service vulnerability has been identified in the Mattermost Playbooks plugin, specifically within versions 10.4.x prior to 10.4.2, 10.5.x prior to 10.5.0, and 9.11.x prior to 9.11.10. The issue arises because these versions do not properly validate the properties used by the RetrospectivePost custom post type. This lack of validation allows an attacker to create a post with maliciously crafted properties, leading to a denial-of-service condition that affects the web application for all users.
