Reflected XSS via unescaped request parameters
Published Mar 7, 2022 · Updated Aug 3, 2024
Reflected XSS in Obtain Infotech WordPress Multisite User Sync/Unsync before 2.1.2 allows remote attackers to run script in a user's browser. The plugin writes the wmus_source_blog and wmus_record_per_page request parameters into HTML attributes without sanitizing or escaping them. A victim must follow a crafted request; successful exploitation runs script in that victim's browser context and can read or alter page data available to the session.
