Magento 1 Security Patching Service

Missing Magento 1 security patches are rarely just a list of files to apply. Older stores can have modified core files, local overrides, extension conflicts and incomplete previous upgrades. We inspect the actual installation, identify which fixes are missing and applicable, then test the store after the changes.

Magento 1 is a legacy platform. Installing historical patches can reduce specific risks, but it does not turn an unsupported Magento 1 installation into a maintained platform. For many Community Edition stores, a controlled move to current OpenMage is the better long-term path. We will not prescribe a Magento 2 rebuild by default.

When a patch installation makes sense

Targeted patching may be the right immediate step when a store cannot move to OpenMage yet, a known fix is missing, or a previous patch failed or left local overrides unprotected. We can also investigate breakage after patching and identify work that belongs in a later modernization plan.

If you are deciding between interim patching and modernization, the public-URL only OpenMage Readiness Test can provide a preliminary starting point. Code-level compatibility still needs review.

This is different from a complete compromise investigation: if malicious code or unauthorized access is suspected, containment and recovery must be scoped separately from installing patches. See our broader Magento security and patching work.

What we verify before changing code

• The Magento edition and version, the existing patch record and the relevant upstream changes. An external security scan can provide leads, but cannot prove every server-side fix or local backport.
• Core-file changes, app/code/local overrides and other customizations that can cause a patch to fail or leave the vulnerable code path in place.
• Publicly identifiable extension risks and the installed extension inventory available with code access. A core patch does not repair an unrelated third-party extension vulnerability.
• The PHP/runtime and deployment constraints, a recoverable backup or staging copy, and the store flows that must be checked before a production cutover.

Historical Magento 1 patch families

The applicable set depends on the exact starting version and changes already present. We do not apply every patch below blindly, nor does this list claim to be a current security baseline. It preserves the patch references visitors to this page commonly need:

• Earlier core fixes: SUPEE-5344, SUPEE-5994, SUPEE-6285, SUPEE-6482, SUPEE-6788, SUPEE-7405 and its v1.1 follow-up, SUPEE-8788, SUPEE-9652 and SUPEE-9767.
• Later core fixes: SUPEE-10266, SUPEE-10415, SUPEE-10570v2, SUPEE-10752, SUPEE-10888, SUPEE-10975, SUPEE-11086, SUPEE-11155, SUPEE-11219, SUPEE-11295, SUPEE-11314 and SUPEE-11346.
• Older or compatibility-specific work can include SUPEE-3762, SUPEE-3941, SUPEE-8167, SUPEE-10336 and SUPEE-11085.

Version-specific exceptions matter. For example, a Magento 1.9.1.1 store may need SUPEE-10497 rather than treating SUPEE-10266 and SUPEE-10415 as an interchangeable pair. For the broader historical index, see the Magento 1 patch list and the patch download reference.

Post-EOL issues require particular care. The old page also referenced CVE-2020-15244, CVE-2020-26252, CVE-2020-26285, CVE-2020-26295, CVE-2021-21426, CVE-2021-21427, CVE-2021-32758 and CVE-2021-32759. These are not one universal Magento 1 patch bundle. Check the actual code and relevant OpenMage fixes or backports before claiming coverage. The former page also listed CVE-2022-24086, which concerns Magento 2 and should not be represented as a Magento 1 patch.

Third-party modules need their own review. Examples from the historical service include EM Ajaxproducts, Cart2Quote, MD Quickview and EM Quickshop. Whether an extension can be patched, updated, disabled or replaced is determined from its installed version and the store’s dependencies.

How the work is carried out

1. Review the store and its history. Establish the version, applied fixes, local overrides, extension inventory and reported symptoms.
2. Choose the appropriate path. Distinguish urgent interim patching from an OpenMage migration or compromise recovery.
3. Prepare a recoverable change. Confirm backups, staging and rollback needs before altering production code.
4. Apply relevant fixes. Resolve patch conflicts and update affected local overrides; check extension fixes as a separately identified scope.
5. Verify critical flows. Test the home page, catalog, customer accounts, checkout, payment and store-specific integrations affected by the change.
6. Cut over and document. Recheck production behavior and record the fixes applied, remaining risks and recommended next steps.

Known regressions are documented in our post-patch troubleshooting guide. Scope, timing and price follow review of the actual store. We do not promise a universal patch bundle or a fixed turnaround before inspecting the code.

Before you contact us

A public store URL, approximate Magento version and the problem you want resolved are enough to start. Do not put passwords, private keys, database exports or customer data in the public form. If code or server access is needed, we arrange a secure handoff after the initial review. If you already have a backup or Git repository, mention it; access is not required in the first message.
