Koha 24.11.19 is a bugfix/maintenance releasei with security patches.

It includes 1 enhancements, 26 bugfixes (3 security).

System requirements

You can learn about the system components (like OS and database) needed for running Koha on the community wiki.

Security bugs

• 42736 SQL Injection in reports/cat_issues_top.pl via Criteria / Filter request parameters (unvalidated string context, no placeholders)
• 42800 Potential XSS in shelf list in the erm module
• 42904 Prevent XSS in patron restriction comments

Bugfixes

About

Other bugs fixed

• 41102 Error 500 on the “About” page when biblioserver Zebra configuration is missing
  

  This fixes the About Koha page when Zebra is not running or not correctly configured in the Koha instance’s koha-conf.xml file. Instead of a 500 error when you access the page, there is now a message in the server information tab for Zebra’s status, such as “Zebra server seems not to be available. Is it started?”.

• 42726 Release team 26.11
  Updates changes to the 25.11 release team, and adds the details of people in the 26.05 release team. (More > About Koha > Koha team.)

Acquisitions

Critical bugs fixed

• 42723 Purchase suggestion 500 page error when EmailPurchaseSuggestions is set to “email address of library”
  

  This fixes a 500 page error[1] when creating a suggestion in the staff interface if:
  – the EmailPurchaseSuggestions system preference is set to “email address of library”, and
  – the library for acquisition information is set to “Any”.

  [1] Can’t call method “inbound_email_address” on an undefined value at /kohadevbox/koha/Koha/Suggestion.pm line 107

Architecture, internals, and plumbing

Critical bugs fixed

• 30233 [ZDI-CAN-29165] 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.

• 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
• 43019 OPAC pages limited to library are readable by unauthenticated users

Other bugs fixed

• 42317 [CVE-2014-1626] Require MARC::File::XML > 1.0.2
  

  This updates the CPAN file to reflect the minimum version
  needed for the MARC::File::XML Perl module. This is important
  because of the vulnerabilities in version 1.0.1.

  (Note: This should not cause any issues, as v1.0.5 is available and already used from Debian repositories for installation.)

• 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)

Cataloging

Other bugs fixed

• 42262 MARC 006 tag editor plugin drops blank value in position 17 when editing existing tag

Circulation

Other bugs fixed

• 41352 Bookings to Collect Help does not take you to the correct place in the manual
  

  This fixes the link to the help for the Circulation > Holds and bookings > Bookings to collect page – it now links to the correct place in the documentation, instead of the documentation home page.

• 41510 Fallback on bookable itemtype can break if item has no itemtype
  Catches the unlikely case of there not being an itemtype associated with item or bib for bookings.

Command-line Utilities

Other bugs fixed

• 40744 Don’t give noisy warning when PatronSelfRegistration is turned off
  

  When PatronSelfRegistration is set to ignore (i.e. do nothing) if –del-exp-selfreg is passed to cleanup_database.pl we were issuing warnings. This patch removes those.

ERM

Other bugs fixed

• 42130 Holdings created in ERM with a linked bibliographic record does not index the record
  

  This fixes indexing of records, so that when a new title is added in the ERM module (ERM > eHoldings > Local > Titles) and ‘Create bibliographic record’ is selected, the new record can be found when searching.

Installation and upgrade (command-line installer)

Critical bugs fixed

• 41337 koha-create –request-db and –populate-db creates log files owned by root (intranet-error.log, opac-error.log)
  

  This fixes the UNIX user/group ownership of the log files intranet-error.log and opac-error.log inside /var/log/koha/<instance>/.
  Previously, running koha-create --request-db followed by koha-create --populate-db would result in the two log files being owned by root/root.
  The correct ownership is now applied, meaning the log files will be owned by the -koha/-koha UNIX user/group.

MARC Bibliographic data support

Other bugs fixed

• 43085 Fix typo in data/marc21_field_006.xml
  

  This fixes the text label shown in the plugin/value builder for MARC21 006 tag when “CF – Computer Files” is selected. The label “12-18 – Undefined” was changed to “12-17 – Undefined”.

  (Change only for Koha 25.05 – made to later releases by Bug 40284 – MARC21: Adjust maxlength for 005, 006 and 007.)

  Sponsored by Toi Ohomai Institute of Technology, New Zealand

OPAC

Other bugs fixed

• 41690 Add MARC21 245$b (subtitle) to Cite option
  

  This fixes citations generated using the “Cite” option in the OPAC – subtitles are now included in the title where they exist for MARC21 (245$b).

Patrons

Other bugs fixed

• 37143 Patron registration allows for saving required fields with a single space instead of information
  

  This changes the OPAC self-registration form validation so that required fields need actual information, and not just spaces.

  Before this, spaces could be entered into most required fields and the form would successfully submit. Now, when submitting, a warning is generated to fill in all missing fields for required fields with just spaces.

Reports

Other bugs fixed

• 8127 Most-circulated items report doesn’t work when limited by library
  

  This fixes some of the filters for the “Most-circulated items” report so that using limits (the Limits section with “Limit to” and “By”) now works.

  Previously some options for “By” (such as Library and Week) generated an error message or there were no results (when results were expected).

• 41292 Add “force_password_reset_when_set_by_staff” to the allowed column name list
  This adds the force_password_reset_when_set_by_staff field in the categories table to the list of allowed password-related fields that can be used in SQL reports.Currently, this field is treated as containing sensitive password-related data and generates an error when creating a report that uses it.

Serials

Other bugs fixed

• 42277 JS error when viewing a subscription

Enhancements

REST API

Enhancements

• 39900 Add public REST endpoint for additional_contents
  

  A new public REST API endpoint has been added for retrieving additional contents (news items and HTML customisations) without authentication. This enables external applications and websites to access and display Koha news and custom content.

  Endpoint details:
  – Path: /api/v1/public/additional_contents
  – Method: GET
  – Authentication: None required (public endpoint)
  – Query parameters:
  – Standard search and filter parameters for finding specific content
  – lang: Filter by language code to retrieve content in a specific language
  – embed: Use translated_contents to include all available translations

  Key features:

  • Public access: No authentication required, making it suitable for displaying library news on external websites
  • Multi-language support: Retrieve content in specific languages or fetch all translations at once using the translated_contents embed
  • Flexible filtering: Search and filter additional contents using standard API query parameters
  • Content types: Access both news items and HTML customisations through the same endpoint

  For developers:

  This endpoint follows the same patterns as other Koha public API endpoints. Use the lang parameter to retrieve content for a specific language, or use embed=translated_contents to get all available translations in a single request. This is particularly useful for multi-lingual library websites that need to display Koha news items.

  Example use cases:
  – Displaying library news on an external website
  – Integrating OPAC announcements into a library portal
  – Building mobile applications that show library notices
  – Creating custom displays of library information
