Admin-level stored XSS via unsanitized tag ID

Published Aug 1, 2022 · Updated Aug 3, 2024

Stored XSS in Microsoft Advertising UET for WordPress before 1.0.4 allows remote authenticated users to execute scripts in visitors' browsers. The plugin stores the UET Tag ID setting without sanitization and interpolates it into front-end tracking script output without escaping. Administrator-level access is required, and a crafted value executes when an affected site's front page is viewed even when unfiltered_html is disabled.
