CVE-2021-24433 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. The simple sort&search WordPress plugin through 0.0.3 does not make sure that the indexurl parameter of the shortcodes "category_sims", "order_sims", "orderby_sims", "period_sims", and "tag_sims" use allowed URL protocols, which can lead to stored cross-site scripting by users with a role as low as Contributor. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
