Stored XSS in Adobe Commerce and Magento Open Source administrative form fields
CVE-2025-54264 is a stored cross-site scripting vulnerability affecting Adobe Commerce, Adobe Commerce B2B, and Magento Open Source. A high-privileged authenticated attacker can inject malicious JavaScript into certain vulnerable form fields in the administrative interface. The payload is stored by the application, typically in the database, and later executes in a victim’s browser when that user visits a page rendering the tainted field. The available context attributes the flaw to insufficient input validation and output encoding on specific form fields. Affected Adobe Commerce versions include 2.4.9-alpha2, 2.4.8-p2, 2.4.7-p7, 2.4.6-p12, 2.4.5-p14, 2.4.4-p15 and earlier; corresponding Magento Open Source and Adobe Commerce B2B branches are also affected as described by Adobe.
