CVE-2024-11183Public exploitNetwork attack vector

Administrator stored XSS via unsanitized settings field

Published Dec 7, 2024 · Updated Dec 9, 2024

Stored XSS in the Rumspeed Simple Side Tab WordPress plugin before 2.2.0 allows remote authenticated users to run scripts through a crafted setting. The pixels_from_top option accepts an attribute-breaking value and returns it to the settings field without sanitization or output escaping. Administrator access and a site that disallows unfiltered HTML, such as WordPress multisite, are required; the script runs in a user's browser when the injected field is hovered.
