CVE-2024-35240Network attack vector

Published May 28, 2024 · Updated Aug 19, 2024

Stored XSS in Umbraco Commerce before 10.0.5 and 12.0.0 through 12.1.3 allows remote attackers to inject script into print output. The published advisory identifies the Print Functionality but does not disclose the input field, code locus, or missing output-neutralization step. Exploitation requires a user to interact with the stored payload, which executes in that user's browser context and can read or modify accessible data.
