Unauthenticated script execution via unescaped search value
Published Nov 21, 2025 · Updated Nov 21, 2025
Reflected XSS in Tainacan 1.0.0 and earlier allows remote attackers to execute scripts in a user's browser through the search parameter. The taxonomy-search template writes the search value directly into an HTML input value attribute without attribute escaping. A victim must open an attacker-crafted link; the resulting script runs in that victim's browser and can read or alter same-origin page content.
