Magento-lts is a long-term support alternative to Magento Community Edition (CE). Versions 20.15.0 and below are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an admin with direct database access or the admin notification feed source to inject malicious scripts into vulnerable fields. Unescaped translation strings and URLs are printed into contexts inside app/code/core/Mage/Adminhtml/Block/Notification/Grid/Renderer/Actions.php. A malicious translation or polluted data can inject script. This issue is fixed in version 20.16.0.
CVE-2025-64174
This medium-severity CVE scores 4.8 under NVD CVSS v3. EPSS exploit probability: 0.0%, top 90% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
