Summary

Testing confirmed that even when a Manager has manage=false for a given collection, they can still perform the following management operations as long as they have access to the collection:

• PUT /api/organizations/<org_id>/collections/<col_id> succeeds (HTTP 200)
• PUT /api/organizations/<org_id>/collections/<col_id>/users succeeds (HTTP 200)
• DELETE /api/organizations/<org_id>/collections/<col_id> succeeds (HTTP 200)

Description

• The Manager guard checks only whether the user can access the collection, not whether they have manage privileges. This check is directly applied to management endpoints. src/auth.rs:816

  
  if !Collection::can_access_collection(&headers.membership, &col_id, &conn).await {
      err_handler!("The current user isn't a manager for this collection")
  }
  

• The can_access_collection function does not evaluate the manage flag. src/db/models/collection.rs:140

  
  pub async fn can_access_collection(member: &Membership, col_id: &CollectionId, conn: &DbConn) -> bool {
      member.has_status(MembershipStatus::Confirmed)
          && (member.has_full_access()
              || CollectionUser::has_access_to_collection_by_user(col_id, &member.user_uuid, conn).await
              || ...
  

• A separate management-permission check exists and includes manage validation, but it is not used during authorization for the affected endpoints. src/db/models/collection.rs:516

  
  pub async fn is_manageable_by_user(&self, user_uuid: &UserId, conn: &DbConn) -> bool {
      let Some(member) = Membership::find_confirmed_by_user_and_org(user_uuid, &self.org_uuid, conn).await else {
          return false;
      };
      if member.has_full_access() {
          return true;
      }
      ...
  

• The actual update and deletion endpoints only accept ManagerHeaders and do not perform additional manage checks. src/api/core/organizations.rs:608
