CVE-2021-24287

43
FAUCET Score

CVE-2021-24287 describes a reflected Cross-Site Scripting (XSS) vulnerability in the Select All Categories and Taxonomies, Change Checkbox to Radio Buttons WordPress plugin versions prior to 1.3.2. This flaw arises from insufficient sanitization of the 'tab' parameter on the plugin's settings page. Rated as Medium severity (CVSS 6.1), this vulnerability requires user interaction (UI:R) and can lead to limited impact on confidentiality and integrity (C:L, I:L). An attacker could inject malicious scripts, potentially leading to session hijacking or defacement. While not listed on CISA's KEV catalog or the Hot List, exploit code is publicly available via ExploitDB and Nuclei templates. Despite this, there is no evidence of active exploitation, and community discussion and media coverage remain minimal.
