CVE-2022-3609Network attack vector

Admin stored XSS via unsanitized partner_hash

Published Dec 12, 2022 · Updated Apr 22, 2025

Stored cross-site scripting in GetYourGuide Ticketing before 1.0.4 allows remote authenticated users to inject scripts via the partner_hash parameter. The plugin fails to sanitize that input and escape it when rendering affected pages, so administrator-level users can store arbitrary web scripts. Exploitation requires a multisite installation or disabled unfiltered_html capability and executes when another user views the injected page.
