CVE-2021-24366

19
FAUCET Score

CVE-2021-24366 describes a Stored Cross-Site Scripting (XSS) vulnerability in the Admin Columns and Admin Columns Pro WordPress plugins prior to versions 4.3 and 5.5.1, respectively. This medium-severity vulnerability (CVSS 5.4) allows high-privilege users, such as administrators, to inject malicious scripts through unsanitized Label settings, even in environments where unfiltered_html is restricted. While the attack requires user interaction (UI:R) and a low privilege level (PR:L), successful exploitation could lead to limited confidentiality and integrity impacts (C:L/I:L). There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
