    CVE-2021-24245

    Published: 6 May 2021Last Modified: 10 Mar 2026

    Summary:

    Details: The Stop Spammers WordPress plugin before 2021.9 did not escape user input when blocking requests (such as matching a spam word), outputting it in an attribute after sanitising it to remove HTML tags, which is not sufficient and lead to a reflected Cross-Site Scripting issue.
