CVE-2015-10098Network attack vector

Script execution via unescaped administrative URLs

Published Apr 8, 2023 · Updated Aug 6, 2024

Cross-site scripting in WPMU DEV Broken Link Checker 1.10.5 and earlier allows remote attackers to execute script in an administrator's browser. Four administrative UI functions insert module identifiers and URLs from add_query_arg(), admin_url(), or get_delete_post_link() into HTML attributes without attribute escaping. Exploitation requires an administrator to open a crafted request, after which attacker-supplied script runs in that WordPress administrative session.
