CVE-2023-41737Network attack vector

Admin stored XSS via unsanitized bar fields

Published Oct 2, 2023 · Updated Apr 28, 2026

Cross-site scripting in WPGens Swifty Bar 1.2.10 and earlier allows remote authenticated users to execute script in visitors’ browsers. Public records do not identify the specific option, field, or function that fails to neutralize stored input before rendering the sticky bar. An administrator-level WordPress account must save the payload, and subsequent visitors can have attacker-controlled script execute in their browsers, enabling page-content manipulation within the site context.
