The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Multiple cross-site request forgery (CSRF) vulnerabilities in Post Revolution 0.8.0c-2 and earlier allow remote attackers to hijack the authentication of arbitrary users for requests to (1) ajax-weblog-guardar.php, (2) verpost.php, (3) comments.php, or (4) perfil.php.

common.php in Post Revolution before 0.8.0c-2 allows remote attackers to cause a denial of service (infinite loop) via malformed HTML markup, as demonstrated by an a< sequence.

Multiple cross-site scripting (XSS) vulnerabilities in common.php in Post Revolution before 0.8.0c-2 allow remote attackers to inject arbitrary web script or HTML via an attribute of a (1) P, a (2) STRONG, a (3) A, a (4) EM, a (5) I, a (6) IMG, a (7) LI, an (8) OL, a (9) VIDEO, or a (10) BLOCKQUOTE element.

Multiple PHP remote file inclusion vulnerabilities in Post Revolution 6.6 and 7.0 RC2 allow remote attackers to execute arbitrary PHP code via a URL in the dir parameter to (1) common.php or (2) themes/default/preview_post_completo.php.
