The .htaccess Redirect WordPress plugin is vulnerable to Reflected Cross-Site Scripting via the link parameter found in the ~/htaccess-redirect.php file which allows attackers to inject arbitrary web scripts, in versions up to and including 0.3.1.

Multiple cross-site request forgery (CSRF) vulnerabilities in the Htaccess module before 7.x-2.3 for Drupal allow remote attackers to hijack the authentication of administrators for requests that (1) deploy or (2) delete an .htaccess file via unspecified vectors.
