Announcing WooCommerce 10.4.3 Update
Introduction to the Latest Release
WooCommerce has unveiled its latest version update, WooCommerce 10.4.3, which brings a series of crucial patches and enhancements. Released on December 22, 2025, this update addresses security vulnerabilities and introduces convenience features beneficial for WooCommerce store owners globally.
Essential Fixes and Updates
Bulgaria's Seamless Currency Transition
As Bulgaria prepares to adopt the Euro on January 1, 2026, WooCommerce steps in to facilitate this transition smoothly. The 10.4.3 update accommodates this economic shift by automatically converting Bulgarian online stores from BGN to EUR. Store owners do not need to intervene, as the update manages this transition based on server time settings, ensuring an effortless adjustment for Bulgarian businesses.
Cart Shortcode Undo Functionality Restored
Version 10.4.2 left some store operators grappling with non-functional 'Undo' actions in cart shortcodes. WooCommerce 10.4.3 rectifies this issue, allowing users to restore items removed from their cart seamlessly. The update addresses premature clearing of the removed_cart_contents data, ensuring a smoother shopping experience.
Resolving HPOS Sync-on-Read Anomalies
The new update also targets HPOS sync-on-read issues, which caused repetitive webhook and Analytics event loops due to unsynchronised modified dates. With version 10.4.3, modified dates align correctly to prevent re-enqueueing of the same events, streamlining database operations during Analytics imports and webhooks.
Addressing Security Concerns
Store API Vulnerability Patch
Security is paramount, and WooCommerce 10.4.3 prioritises safeguarding customer data. A discovered vulnerability in the Store API permitted authenticated users to access sensitive guest order details across versions 8.1 to 10.4.2. This exposed data could potentially be misused. The latest update successfully closes this security gap.

Who Should Update?
Considering the critical security patch, it is advisable for all WooCommerce store owners to upgrade to version 10.4.3 promptly. Stores benefiting from automatic updates or those hosted on Automattic platforms,such as WordPress.com, Pressable, VIP, and WP Cloud,should find that their systems have been automatically patched.
Should I Wait to Update?
If you are contemplating whether to update now or delay, it's best to act swiftly, especially due to the security enhancements provided. Prompt updates protect customer data integrity and ensure that any functionality issues like the ones addressed in this release are resolved.
How Will These Changes Impact My Store?
The alterations brought by WooCommerce 10.4.3 are designed to enhance store functionalities sustainably. The automatic currency conversion supports Bulgarian businesses in strengthening their market capabilities, while other fixes contribute to a more reliable and secure platform. Embracing these enhancements ensures that your store remains competitive and secure in an ever-evolving e-commerce environment.
