CiviCRM v2+ includes a "Custom Search" system which allows administrators to register customized search forms and includes some default custom-searches (e.g. "Find Contribution Amounts by Tag"). CiviCRM also supports role-based access controls using permissions like "access CiviContribute" or "access CiviEvent". For the default custom-searches, CiviCRM does not enforce the expected role-based access controls.

For example: If a security policy grants a user permission to view the CiviCRM backend ("access CiviCRM") but denies permission to view contribution data ("access CiviContribute"), then the user may still access contribution data through a custom-search.

This vulnerability is mitigated by the fact that the access controls can only be bypassed by users with the permission "access CiviCRM".
