CVE-2021-24954Network attack vector

Administrator-session script execution via unescaped dashboard attribute

Published Dec 13, 2021 · Updated Aug 3, 2024

Reflected XSS in ProfilePress before 3.2.3 allows remote attackers to run script in an administrator's browser via a crafted dashboard request. The admin dashboard handler copies the unsanitized ppress_cc_data request value into an HTML attribute without context-appropriate escaping. Exploitation requires an administrator to open the crafted request; injected script runs in that dashboard origin and can read or modify data available to that session.
