Horizon Alert
Summary of the vulnerability and why it matters
This advisory concerns a stored Cross-Site Scripting (XSS) vulnerability in Adobe Commerce. The issue allows attackers to inject malicious scripts into form fields, which could then be executed in a user's browser. This could potentially lead to unauthorized access or control of a victim's account or session.
- Attackers can insert harmful code into forms.
- High impact if users visit affected pages.
- Confirm if Adobe Commerce is in use.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this vulnerability by targeting public-facing form fields within Adobe Commerce. Users who interact with these compromised fields, or view pages containing them, may inadvertently trigger the injection of malicious scripts. This could lead to unauthorized execution of JavaScript in their browser, potentially resulting in elevated access or control over their account or session.
- No authentication required for attacker.
- Malicious script injected via form fields.
- Risk of account takeover or session hijacking.
Live Threat

Operational Fix
Recommended remediation, mitigation, and detection steps
Adobe Commerce's stored XSS vulnerability impacts product owners and the infrastructure teams supporting the e-commerce platform. The first practical step is to inventory all Adobe Commerce instances, assess their internet exposure, and identify the business owner for each. Subsequently, remediation plans should be developed based on the assessed risk and criticality, prioritizing instances that are externally accessible and actively used.
- Product owners must own the remediation effort.
- Verify external accessibility and business criticality.
- Plan for vendor coordination and patching.
