Script execution via unescaped collection URL
Published Apr 16, 2024 · Updated Apr 8, 2026
Reflected XSS in Tainacan Interface 2.7.2 and earlier allows remote attackers to execute scripts through a crafted collections URL. The archive-tainacan-collection.php template uses add_query_arg on the request URL and emits the result without appropriate escaping. No authentication is required, but a victim must follow the malicious link before the injected script runs in the victim's browser.
