description

Drupal Entity Reference Manager (Merge entities) versions through 1.0.3 have an authorization flaw in the merge functionality. A user with only content-viewing permissions may be able to access and perform merge operations by directly reaching the tool.

mitigation

Restrict access to the Merge entities tool and its routes to explicitly authorized roles, and review existing role permissions. Upgrade to a vendor release newer than 1.0.3 once a confirmed fixed release is available.

fixed in 1.0.3
