System requirements

Security bugs

• 30233 Remote code execution in user-supplied regex
  

  This change refactors the regular expression handling for Batch Item Modification, MARC Modification templates, and Callnumber splitting. It moves from Perl’s traditional compile-time regular expression handling to a more dynamic (but restrictive) run-time regular expression handling more similar to Python’s “sub” regex method. This functions to reduce vulnerabilities to code injection into Koha’s Perl backend.

• 42471 /cgi-bin/koha/suggestion/suggestion.pl Multiple Parameters Stored Cross-Site Scripting
• 42746 Stored SQL injection via unvalidated ‘agefield’ in automatic_item_modification_by_age (C4::Items::ToggleNewStatus)
• 42747 Stored SQL injection via patroncard layout image_name (patroncards/edit-layout.pl -> create-pdf.pl)
• 42749 SQL injection in acqui/parcels.pl via the orderby parameter (ORDER BY direction) reaching C4::Acquisition::GetInvoices
• 42847 SIP authentication ignored after initial successful connection
• 42866 SQL Injection in Koha/AdditionalContents.pm search_for_display via the patron lang value (stored / second-order, executed on issue-slip print, unvalidated string context, no placeholder)
• 43019 OPAC pages limited to library are readable by unauthenticated users

Bugfixes

Accessibility

Other bugs fixed

• 42229 Form label used on non-form elements on opac-memberentry.tt pages
• 42232 Fieldset with missing legend on OPAC account messaging settings page (opac-messaging.tt)
  

  This fixes an accessibility issue on the patron’s OPAC account messaging preferences form: Missing legend for the fieldset with submit changes and cancel buttons.

  It adds a legend tag “visible” for screen reader patrons so that it is clear for the group of buttons what they are being asked to do.

• 42233 OPAC suggestions table header contains no text
• 42234 OPAC checkout history page table header contains no text
  This fixes the patron checkout history table in the OPAC. It adds a title to the cover image column (“Cover image”).
• 42299 OPAC detail page: star ratings has no associated label
  This fixes an accessibility issue for star ratings on the OPAC record details page – it adds a label for screen reader patrons.

Acquisitions

Other bugs fixed

• 42919 Suggestion duplicate warning erases suggestion info

Cataloging

Other bugs fixed

• 41829 Tag editor button has wrong id on copied MARC field when value builder plugin is used

  Sponsored by Koha-Suomi Oy

• 42178 The Close button submits the remove from bundle form

  Sponsored by Lund University Library

• 42972 [25.11.x] Cannot add, edit, or delete MARC overlay rules

Circulation

Other bugs fixed

• 41992 Checkout History remembering Last Page

Hold requests

Other bugs fixed

• 42395 Missing translations for the existing holds table (load_patron_holds_table) for a record in the staff interface
  

  This fixes the translatability of strings for the existing holds table in the staff interface for a record (Staff interface > [details page for a record] > Holds > Existing holds).

  These strings were not previously translated:

  • Priority column: In transit, Waiting, and In processing
  • Change priority column: tooltip text for arrows:
    . Move hold up
    . Move hold to top
    . Move hold to bottom
    . Move hold down

Patrons

Other bugs fixed

• 42245 Patron search for guarantors is preselecting borrower sort values from the borrower record
  

  This fixes the “Add guarantor” pop-up window when adding a guarantor for a patron.

  The form was populating the “Sort 2” field with the value from the patron you are adding the guarantor to (if they had values stored for the Sort 1 and Sort 2 fields in the library management section).

• 42781 Declare ‘name’ before using it in patron-format.js

Searching – Elasticsearch

Critical bugs fixed

• 42485 Elasticsearch dynamic mapping date detection causes indexing failures with ARRAY MARC format

Serials

Other bugs fixed

• 42844 Subscription search breaks when using additional field and no search result is returned

Templates

Other bugs fixed

• 42518 Capitalization: Refund Payout Receipt
  

  This fixes the capitalization (title case to sentence case) for a heading in the “Point of sale payout receipt (PAYOUT)” print notice template: Refund Payout Receipt –> Refund payout receipt.

  Note: This only affects new Koha installations. Existing installations need to either manually update the notice or replace the existing notice with the default notice text.

• 42695 Minor language and markup corrections to reports error messages
  

  This fixes the HTML markup for some report error messages, along with some minor text changes:

  • Uses an H1 for the heading
  • Uses p for paragraphs
