ALERT: 14 XSS JAN 2021 – Cross-Site Scripting JAN 2021 Blast
WordPress Security Report
Be informed about the latest Cross-Site Scripting, identified and reported publicly in January 2022. As these XSS JAN 2021 vulnerabilities have a severe negative impact on any WordPress Security, consider our FREE security AUDIT.
An estimated 1.692.000 active WordPress installations are susceptible to this attack type, considering only the publicly available numbers. The estimated number can increase by 20-25% with premium versions as they are private purchases.
Furthermore, the initial estimation can triple if we consider the already patched versions BUT NOT UPDATED by owners, as the vulnerability remains active within their domain. As these owners start changing their hosting provider (due to constant unexplained issues), they actively migrate these vulnerabilities behind protected areas, possibly exposing other clean WP to different attack types.
It is a 27% increase compared to December 2020. Read more about our previous report here: 11 XSS – Cross-Site Scripting – WordPress Security DEC. The following cases made headlines PUBLICLY just last month in the XSS JAN 2021 category:
