CVE-2021-24317Public exploitNetwork attack vector

Script execution via unsanitized page parameters

Published Jun 1, 2021 · Updated Aug 3, 2024

Cross-site scripting in PureThemes Listeo before 1.6.11 allows attackers to execute browser scripts through crafted page parameters. The search page reflects keyword_search and location_search without proper sanitization, while booking and message fields store attacker-controlled markup. The search path is unauthenticated but requires a visitor to open a crafted result; booking and messaging injection requires authentication and persists for later viewers.
