Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a Cross-Site Scripting (XSS) vulnerability in the Easy Digital Downloads (EDD) PDF Stamper extension for WordPress. The vulnerability stems from misuse of WordPress's add_query_arg function, which does not automatically escape output.
