CVE-2024-12844Public exploitNetwork attack vector

Administrator script execution via unsanitized tag reflection

Published Dec 20, 2024 · Updated Dec 27, 2024

Reflected XSS in /admin/store.php in emlog Pro 2.4.0 and 2.4.1 allows remote attackers to execute scripts through a crafted tag value. The endpoint concatenates the tag parameter directly into HTML output without validation, sanitization, or contextual encoding. An administrator must open the crafted URL, after which the injected script runs in that administrator's browser context and can expose the session cookie.
