Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE CVE-2021-24503
CVSS Medium (5.4)
Publicly Published July 5, 2021
Last Updated January 22, 2024
Researcher apple502j
Description

The Popular Brand Icons – Simple Icons WordPress plugin before 2.7.8 does not sanitise or validate some of its shortcode parameters, such as "color", "size" or "class", allowing users with a role as low as Contributor to set Cross-Site payload in them. A post made by a contributor would still have to be approved by an admin to have the XSS triggered in the frontend, however, higher privilege users, such as editor could exploit this without the need of approval, and even when the blog disallows the unfiltered_html capability.
