This is not a security vulnerability. It is a mitigation to protect against misconfiguration.

CiviCRM includes a large number of configurable permissions. Administrators may assign these permissions to various users and roles. This is powerful functionality that accommodates diverse needs, but it provides the opportunity for misconfiguration.

Misconfigurations may arise for a few reasons, such as:

  • Misunderstandings - A permission named "access CiviContribute" is ambiguous. It can be interpreted to mean "access CiviContribute like a staffer" or "access CiviContribute like a member of the public" or "access CiviContribute like an administrator". One must look past this technical name to find a meaning.
  • Subjectivity - "Appropriate" and "inappropriate" permissions depend on the organization, its people, its goals, etc.

The current update includes an additional guardrail to protect against misconfiguration. For example, "access CiviContribute" is intended for backend (staff/volunteer/fundraising) users who manage contributions. It is hard to imagine ever granting "access CiviContribute" to anonymous users (except in that the name is ambiguous). This misconfiguration will now produce a warning.

This update is not exhaustive, and future monthly iterations may refine the advice and detection for unusual configurations.
