Descriptions

Mattermost versions 9.5.x <= 9.5.3, 9.6.x <= 9.6.1 and 8.1.x <= 8.1.12 fail to perform proper input validation on post actions which allows an attacker to run a playbook checklist task command as another user via creating and sharing a deceptive post action that unexpectedly runs a slash command in some arbitrary channel.

Las versiones de Mattermost 9.5.x &lt;= 9.5.3, 9.6.x &lt;= 9.6.1 y 8.1.x &lt;= 8.1.12 no realizan una validación de entrada adecuada en las acciones posteriores, lo que permite a un atacante ejecutar un comando de tarea de lista de verificación del libro de jugadas como otro usuario creando y compartiendo una acción de publicación engañosa que ejecuta inesperadamente un comando de barra diagonal en algún canal arbitrario.
