CVE-2023-48756Network attack vector

Reflected script execution via unsanitized input

Published Dec 14, 2023 · Updated Apr 28, 2026

Cross-site scripting in JetBlocks for Elementor 1.3.8 and earlier allows remote attackers to execute scripts in a victim's browser via crafted requests. Public advisories do not identify the vulnerable parameter or function; the plugin fails to sanitize input before reflecting it into generated pages. An attacker needs no account but requires a victim to follow a crafted link, enabling script actions in that victim's web session.
