On September 7, 2026, Adobe released an official fix for StyleSmuggler, the critical vulnerability disclosed by security firm Sansec two days earlier. If you run Magento or Adobe Commerce, that patch is the one most stores needed.
It just doesn’t reach everyone. Adobe’s official StyleSmuggler patch stops at Adobe Commerce 2.4.4 and Magento Open Source 2.4.6. If your store runs anything older, from 2.2.0 up through 2.4.3-p3, Adobe’s official StyleSmuggler patch does not cover it.
We rebuilt Adobe’s fix for every one of those older releases: 41 versions in total, from Magento 2.2.0 to 2.4.3-p3. Each is a single patch file built for your exact version, and you can download the full bundle below.
Who this is for
Check your edition and version against Adobe’s official coverage:
| Edition | Adobe’s hotfix covers | No patch from Adobe |
|---|---|---|
| Adobe Commerce | 2.4.4 to 2.4.9 | below 2.4.4 |
| Adobe Commerce B2B | 1.3.3 to 1.5.3 | below 1.3.3 |
| Magento Open Source | 2.4.6 to 2.4.9 | 2.4.5 and below |
If you’re in the right-hand column, this patch bundle is for you. If you’re in the left-hand column, apply Adobe’s official hotfix instead. Our guide to Adobe’s official fix for the StyleSmuggler vulnerability (CVE-2026-75650) covers which versions it fits and how to apply it.
🚀 Quick takeaway
Adobe’s patch reaches Adobe Commerce 2.4.4 and Magento Open Source 2.4.6. Anything older, including every Magento 2.2 and 2.3 release, needs this backport instead.
About StyleSmuggler
StyleSmuggler is Sansec’s name for CVE-2026-75650, Adobe’s APSB26-146, a flaw in the Magento and Adobe Commerce core with a CVSS score of 10.0, the maximum possible. An unauthenticated attacker, with no login and no user interaction, can run code on the store’s server, reach its data, and plant a persistent backdoor.
The first confirmed attack on a live store happened on September 4, 2026, and took roughly 50 minutes from first contact to full takeover. Running an older, unsupported release means there is no protection with the official patch. For the full incident, including how we protected client stores before Adobe published any guidance, read our rapid-response post.
Why older versions were left without a fix
Adobe’s hotfix (VULN-39341) changes nine core files. Adobe built and tested it only for versions still in its support window: Adobe Commerce from 2.4.4, and Magento Open Source from 2.4.6. Everything below that is out of official support, so it receives no patch, regardless of how many live stores still run it, and many do.
We took Adobe’s fix and rebuilt the same nine-file change for every version back to Magento 2.2.0, adapting it to the differences in each release. There are now 41 version-specific patches ready within a day of Adobe’s own release.
The patch bundle
The bundle contains 41 patch files, one per Magento version, covering:
- Magento 2.2: 2.2.0 through 2.2.11
- Magento 2.3: 2.3.0 through 2.3.7-p4, including all interim patch releases
- Magento 2.4: 2.4.0 through 2.4.3-p3, including all interim patch releases
Enter your email to download the StyleSmuggler patch bundle for older Magento versions, one patch file per version, from 2.2.0 to 2.4.3-p3.
How to apply the patch
Same four steps as the standard patch: stage it first and take a snapshot you can roll back to, apply the patch for your exact version (from your Magento root: patch -p1 < VULN-39341_<version>.patch), test the shopping journey, cart, checkout, payment, and transactional email, then repeat on production.
The only thing that changes on an older version is which file you grab. The 41 patches aren’t interchangeable, so match yours exactly.
Mandatory credential rotating
Applying the patch does not, on its own, fully secure a store. The flaw can expose your store’s encryption key, and that key protects integration tokens, payment gateway credentials, and system automation tokens, so you need to rotate everything it may have touched.
After applying the patch, rotate admin panel user passwords, REST, SOAP, and GraphQL integration tokens (deactivate and regenerate), OAuth client secrets for connected apps, payment gateway API credentials, at the provider (Stripe, Braintree, Adyen, PayPal, and so on), database credentials, SSH and deploy keys, and any cron or system service-account credentials, and API keys for shipping, tax, and other third-party extensions.
Rotating the encryption key alone does not invalidate credentials that were already captured, so any that were exposed stay usable until rotated at their source. If you’re not sure what’s still connected to your store, we can map it and rotate everything for you.
Older Magento versions are the trickiest to patch safely, and an upgrade is often the better long-term answer. Reach out, and we will check your store for a break-in and apply the right patch for your version. We can also plan an upgrade to a supported version so you’re back inside Adobe’s security support for the future. Start with a free security check, or talk to our Magento team.
Frequently asked questions
Is there an official Adobe patch for Magento 2.2 or 2.3?
No. Adobe’s hotfix only covers Adobe Commerce 2.4.4 and up, Adobe Commerce B2B 1.3.3 and up, and Magento Open Source 2.4.6 and up.
Which versions does scandiweb’s backport cover?
41 versions, Magento 2.2.0 through 2.4.3-p3, every interim release included. The full breakdown is above.
Do I still need to patch an end-of-life store?
Yes. StyleSmuggler doesn’t check whether Adobe still supports your version, only whether the vulnerable code is there. An end-of-life store is exposed exactly like a current one.
Is the patch enough on its own?
No. It closes the hole, but it doesn’t remove an attacker who’s already in, and it doesn’t invalidate credentials that were already exposed. Check for compromise and rotate your credentials too.
