Published: 26 October 2026 | DX3webs Security Advisory
A recently disclosed security incident involving the eMudhra certificate authority has prompted emergency security updates across the internet.
Although operating system vendors, browser developers and security providers have responded rapidly, some Magento and other ecommerce applications may still contain outdated SSL certificate bundles.
Security monitoring tools such as Sansec eComscan are now detecting these files and alerting website administrators.
At DX3webs, we’re reviewing the implications for our hosting infrastructure and helping customers understand what needs to be updated.
What has happened?
In October 2026, researchers discovered that private keys belonging to eight intermediate certificate authorities operated by eMudhra had been generated using insufficiently secure cryptographic randomness.
This potentially allows attackers to reproduce the affected keys and issue fraudulent SSL certificates for websites they do not own.
SSL certificates are fundamental to secure internet communication. They allow applications to verify that they’re communicating with the intended server.
For example, a Magento website connecting to a payment provider such as Stripe needs to verify that the remote server really belongs to Stripe.
If an attacker can present a fraudulent certificate that the application accepts, they could potentially impersonate that service and intercept or manipulate communications.
Importantly, this is not a weakness in the SSL/TLS encryption algorithms themselves. The problem concerns the certificates and authorities used to establish trust.
Why is Sansec eComscan reporting this?
Sansec has introduced detection for certificate bundles that still contain affected certificate authorities.
You may see an alert similar to:
File system scan – AT RISK
Detection:
compromised_certificate_authority
Certificate:
emSign ECC Root CA - G3
Common affected files include:
Composer:
vendor/composer/ca-bundle/res/cacert.pemStripe PHP SDK:
vendor/stripe/stripe-php/data/ca-certificates.crtWordPress:
wp-includes/certificates/ca-bundle.crtThese files contain lists of trusted certificate authorities used when applications make secure HTTPS connections.
If an outdated bundle still trusts an affected authority, software using that bundle may remain exposed even after the server’s operating system has been patched.
Does this mean my website has been hacked?
No.
An eComscan warning does not mean your Magento installation has been compromised, that customer data has been stolen or that payment transactions have been intercepted.
It indicates that an outdated certificate bundle has been identified and requires attention.
It is nevertheless a legitimate security concern and should be addressed promptly.
Why doesn’t updating the server fix everything?
There are two separate places where certificate trust is managed.
1. Operating-system certificates
Linux distributions maintain their own trusted certificate stores.
On Ubuntu, these are generally managed through the ca-certificates package.
Canonical released security updates on 20 October 2026 to remove trust in the affected certificate authority.
Hosting providers and system administrators are responsible for ensuring these operating-system updates are applied.
2. Application certificate bundles
Magento, WordPress and third-party PHP libraries can include independent certificate bundles within their application files.
These may be used instead of the operating system’s certificate store.
Consequently, an operating system can be fully patched while an ecommerce application continues to contain outdated certificates.
This is why eComscan may report an issue within Magento’s vendor/ directory even when the underlying server has already received the relevant security update.
What should Magento developers do?
We recommend reviewing all affected certificate bundles and updating them through the application’s normal dependency management and deployment process.
Step 1: Review the Sansec findings
Identify the specific files reported by eComscan.
Do not assume every certificate-related warning requires the same solution.
Determine which component owns each affected file and whether a patched vendor release is available.
Step 2: Update Composer’s CA bundle
The maintainers of composer/ca-bundle released version 1.6.0 on 20 October 2026, incorporating protections against the compromised eMudhra certificates.
For applications using Composer, the relevant package can be updated with:
composer update composer/ca-bundleFor production Magento installations, developers should first perform a dry run, review dependency compatibility and ensure the update does not introduce unrelated package changes.
The resulting composer.lock changes should be committed to the application’s source repository and included in its normal deployment process.
Avoid performing unrestricted Composer upgrades on live Magento stores simply to resolve this certificate issue.
Step 3: Review the Stripe PHP SDK
Some versions of the Stripe PHP library contain their own CA certificate bundle:
vendor/stripe/stripe-php/data/ca-certificates.crtIf Sansec identifies this file, the developer should check whether the installed Stripe release includes an updated certificate bundle.
Where a fixed vendor release is unavailable, Sansec recommends temporarily replacing the affected bundle with the current Mozilla CA bundle available from:
Back up the original file, verify the downloaded replacement and test HTTPS communication with the payment provider before considering the remediation complete.
Do not disable SSL certificate verification to work around certificate errors.
That would undermine the security protections the update is intended to restore.
Step 4: Check WordPress and other applications
This issue is not exclusive to Magento.
WordPress and other applications may contain their own trusted certificate files.
Developers should review affected bundles and apply the appropriate application or vendor updates.
Manual replacement of bundled certificates may be temporary. Subsequent application updates or Composer deployments can restore older files, potentially causing the warning to reappear.
Any interim remediation should therefore be tracked until a permanent vendor-supported fix is available.
Step 5: Test and rescan
Following remediation, developers should:
- Confirm the affected certificates have been removed or explicitly distrusted.
- Verify outbound HTTPS connections continue to work.
- Test critical integrations, particularly payment gateways and external APIs.
- Confirm no unrelated application dependencies have changed.
- Rerun Sansec eComscan and verify the findings are resolved.
- Ensure the fix survives the next normal deployment.
What is DX3webs doing?
DX3webs takes infrastructure security seriously, and we are assessing the implications of this disclosure across our managed hosting environment.
Our responsibilities include reviewing operating-system certificate trust stores, applying applicable vendor security updates and maintaining the security of the underlying hosting infrastructure.
We have also confirmed the availability of Canonical’s updated certificate packages for supported Ubuntu releases.
However, libraries distributed within an individual customer’s Magento or WordPress application are normally maintained through that application’s development and deployment process.
Where security monitoring identifies an affected application dependency, we recommend that customers involve their development team promptly.
DX3webs can assist with identifying the relevant files, checking the server environment and coordinating remediation where required.
A positive example of the industry’s response
One encouraging aspect of this incident has been the speed of the wider security community’s response.
Browser vendors, operating-system maintainers, certificate authorities, Cloudflare, Composer and specialist ecommerce security providers have all contributed to identifying and reducing exposure.
The response also demonstrates the value of layered security monitoring.
Operating-system updates address vulnerabilities at the infrastructure level, while tools such as Sansec eComscan can identify outdated or insecure components buried within individual applications.
Both are important.
Our advice
If you have received a Sansec eComscan warning referencing compromised_certificate_authority, don’t panic — but don’t ignore it.
The alert does not establish that your website has been compromised.
It does mean that a potentially unsafe certificate trust configuration has been detected and should be investigated.
For Magento store owners, the recommended action is to forward the alert to your development team and arrange for the affected application dependencies to be updated and tested.
DX3webs customers who need assistance identifying whether a finding relates to their hosting environment or application code are welcome to contact our support team.
