Executive brief
Adobe Commerce, a popular e-commerce platform used by many online retailers, contains a stored cross-site scripting (XSS) vulnerability in form fields. An attacker with low-level account privileges can inject malicious scripts into these fields, which are then executed when other users—including administrators—view the affected pages. This could allow attackers to hijack accounts, steal session data, or compromise customer information.
Technical details
The vulnerability is a stored (persistent) cross-site scripting flaw in Adobe Commerce form field handling that fails to properly sanitize or encode user-supplied input. A low-privileged attacker can inject malicious JavaScript into vulnerable form fields; when authenticated users or administrators browse to pages containing the poisoned data, the script executes in their browsers with their privileges. The scope is changed, indicating the attacker may be able to impact resources beyond their own account. No patch details are available from the provided references, though Adobe's advisory APSB26-92 would contain remediation guidance.
