This page gives an overview about how Magnolia handles security.
Overview: JAAS, users, groups, roles and permissions
Magnolia security is based on Java Authentication and Authorization Service (JAAS). JAAS provides a standardized way for:
- Authentication: Reliably and securely determine who is using the system and provide them with means to sign into the application.
- Authorization: Ensure that users have the permissions to do the actions required such as editing pages or creating categories.
The system always checks whether a certain user has the required (set of) permissions to access a certain resource such as a web page, document, template or some other type of data. Permissions such as Access Control Lists (ACLs) are assigned to user roles. The roles can be assigned to groups or directly to the users. Finally, users can be assigned to a group.
For more details please refer also to the following pages:

Magnolia Security app
Use the Magnolia Security app to administer Users, Groups and Roles with ACLs that Magnolia provides. By default, the app stores the user, group and role data in the
userroles JCR workspaces.
Web access security
Every request sent to Magnolia is checked by the URISecurityFilter. The filter checks whether the role(s) of the requesting user allow(s) the user to request a given path with the given method.
Web permissions are granted as web access lists per role. They grant access to a path for Get or Get & Post.
- Get – Grants the HTTP
GETmethod for a given URI.
- Get & Post – Grants the HTTP
DELETEmethods for a given URI.
Magnolia uses the Jackrabbit reference implementation of the Java Content Repository (JCR) 2.0 standard. ACL checks are performed at the JCR level. This low-level checking has the following benefits:
- Better performance than checking in the application code.
- Repository can be exposed to third-party apps. Access Control Lists (ACLs) still apply.
- Use JCR API directly without the need to wrap objects.
Since content and templates are usually customized or completely developed by the users of Magnolia, it is the responsibility of the users to ensure that developed content is not exploitable by cross-site scripting, HTML injection or similar attacks. For templates provided with Magnolia, the system tries to ensure that there are no such vulnerabilities.
External security is achieved via servlet container features. The strength of the security depends on the container used to run Magnolia. To improve the security, Magnolia recommends that you run the Apache Web Server or another proxy server in front of the application server.
