From b8a31dcc72703b4cd597e4ce681abcf6b0a3d507 Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Thu, 6 Feb 2014 09:04:10 +0100 Subject: Do not allow unauthenticated users to delete comments Since commit fb7bde3 (Add support for anonymous comments, 2014-02-04), we support comments with no specific author. Add a check to canDeleteComment() and canDeleteCommentArray() to ensure an unauthenticated user cannot delete such comments.
