From 602cc0a478b8cbe73e6b947acd1c4f4bf273ea96 Mon Sep 17 00:00:00 2001 From: Marcel de Rooy Date: Tue, 7 Feb 2017 09:09:33 +0100 Subject: [PATCH] Bug 18019: Add CSRF protection to authorities-home.pl (op==delete) Content-Type: text/plain; charset=utf-8 Without this patch, it is possible to delete authority records with URL manipulation. Like: /cgi-bin/koha/authorities/authorities-home.pl?op=delete&authid=[XXX] Test plan: [1] Go to Authorities. Search for some authorities (without links). [2] Delete an authority. Should work. [3] Construct an URL like above to delete another authority. Should fail. Under Plack this results in an internal server error, the log tells you: Wrong CSRF token.
