CVE-2022-33943Network attack vector

Contributor-level stored XSS via unsanitized parameters

Published Jul 27, 2022 · Updated Apr 28, 2026

Stored XSS in Nico Amarilla BxSlider WP 2.0.0 and earlier allows remote authenticated users to inject script through plugin parameters. The plugin stores some contributor-supplied parameters without sanitizing them and renders them without output escaping; public sources do not identify the affected fields or code locus. Contributor access is sufficient, and victim interaction is required before the stored script runs in a visitor's browser and can read or alter data available to that site session.
