From 51203d8cea7c71bb96f7783c83b5f9fcbc12cf2a Mon Sep 17 00:00:00 2001 From: Aleisha Amohia Date: Tue, 16 Mar 2021 10:41:53 +1300 Subject: [PATCH] Bug 27961: Ensure external URLs are filtered TT variables are used to build the link in items.uri . This is a problem particularly when TrackClicks is enabled because the items.uri value doesn't get escaped, resulting in a 404. To test: 1) Enable the TrackClicks system preference (set to Track or Track anonymously) 2) Find a record with an item 3) Edit the item and put an external URL under the Uniform Resource Identifier field 4) Go to that record in the OPAC 5) Click on Link to resource 6) Confirm you are not redirected to the URL and instead see a 404 7) Apply the patch and refresh the page 8) Click on Link to resource 9) Confirm you are redirected as expected 10) Go back to the staff client to edit your item. This time put two URLs in the Uniform Resource Identifier field, separated by ' | '. (Don't forget the spaces around the pipe, and don't forget to add a trailing slash to the URL). 11) Go back to the OPAC and refresh the page. 12) Confirm both URLs redirect as expected.
