EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2024-41676 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,156 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Impact
This XSS vulnerability is about the system configs
- design/header/welcome
- design/header/logo_src
- design/header/logo_src_small
- design/header/logo_alt
They are intended to enable admins to set a text in the two cases, and to define an image url for the other two cases. But because of previously missing escaping allowed to input arbitrary html and as a consequence also arbitrary JavaScript.
While this is in most usage scenarios not a relevant issue, some people work with more restrictive roles in the backend. Here the ability to inject JavaScript with these settings would be an unintended and unwanted privilege.
Patches
Has the problem been patched? What versions should users upgrade to?
The problem is patched with Version 20.10.1 or higher.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
Possible mitigations are
- Restricting access to the System Configs
- checking templates where these settings are used to apply proper html filtering
For Users relying on this possibility
Some Users might actually rely on the ability to use html there.
You can restore the previous behavior by making use of the new introduced ->getUnescapedValue() method on this escaped elements. Developers should have a look at the newly introduced Mage_Core_Model_Security_HtmlEscapedString

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openmage/magento-lts, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update openmage/magento-lts to 20.10.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-41676 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-41676 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-41676. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-41676 in your dependencies?
O3 Security finds CVE-2024-41676 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
