CVE-2022-28586Public exploitNetwork attack vector

Browser script execution via bypassable content filtering

Published Apr 25, 2022 · Updated Aug 3, 2024

Cross-site scripting in Hoosk 1.8.0 page editing allows remote attackers to execute JavaScript in another user's browser. Hoosk_model.php's updatePage method accepts the content POST value into sirTrevorInput, and its special-character filter fails to neutralize crafted script payloads before page content is rendered. Execution requires a victim to view the attacker-controlled page and is confined to the permissions and data available in that browser session.
