SUPEE-11346: Final Security Patch for Magento 1

Adobe has released SUPEE-11346, the final security patch for both Magento Commerce 1 and Magento Open Source 1. This patch addresses critical security vulnerabilities and represents the absolute last security update that will be made available for the legacy platform.

What SUPEE-11346 Addresses

Like all SUPEE patches before it, SUPEE-11346 targets critical vulnerabilities that could expose merchants and their customers to risk. The specific vulnerabilities addressed include issues that could potentially allow unauthorised access or data compromise if left unpatched.

For retailers still operating on Magento 1, applying this patch is essential before support ends. It represents a final opportunity to address known security exposures on the legacy platform.

Installation Considerations

Applying SUPEE-11346 requires careful testing before production deployment. Retailers should establish a staging environment that mirrors their production setup, test the patch thoroughly, and validate that all extensions and customisations remain functional after the update.

The patch installation process follows standard Magento procedures. However, given this is the final patch for Magento 1, merchants should also use this opportunity to assess their migration timeline. The effort required to apply and test this patch should be considered in the context of broader platform modernisation plans.

Beyond the Final Patch

With SUPEE-11346 released, merchants face a critical reality: no further security updates will be available for Magento 1. Any vulnerabilities discovered after this point will remain unpatched, creating ongoing risk exposure.

This limitation underscores the urgency of migration planning. Retailers who have deferred the Magento 1 to Magento 2 transition should accelerate their timelines. Staying on an unsupported platform with known vulnerabilities introduces unacceptable risk to business operations and customer trust.

Moving Forward Securely

Applying SUPEE-11346 is a necessary but interim step. The real priority must be planning and executing migration to a modern, actively supported platform. Adobe Commerce (Magento 2) offers not only security and stability but also the features and performance capabilities required to compete in today's e-commerce landscape.

Merchants who have already upgraded to Magento 2 benefit from regular security updates and ongoing vendor support. For those still considering the move, the release of this final patch should serve as a catalyst for action. Security in e-commerce is not negotiable.
