Invision Community before 4.7.16 allow SQL injection via the applications/nexus/modules/front/store/store.php IPS\nexus\modules\front\store\_store::_categoryView() method, where user input passed through the filter request parameter is not properly sanitized before being used to execute SQL queries. This can be exploited by unauthenticated attackers to carry out Blind SQL Injection attacks.

A Server-Side Request Forgery (SSRF) vulnerability in IPS Community Suite before 4.6.2 allows remote authenticated users to request arbitrary URLs or trigger deserialization via phar protocol when generating class names dynamically. In some cases an exploitation is possible by an unauthenticated user.

Invision Community (aka IPS Community Suite or IP-Board) before 4.6.5.1 allows stored XSS, with resultant code execution, because an uploaded file can be placed in an IFRAME element within user-generated content. For code execution, the attacker can rely on the ability of an admin to install widgets, disclosure of the admin session ID in a Referer header, and the ability of an admin to use the templating engine (e.g., Edit HTML).

Invision Community (aka IPS Community Suite or IP-Board) before 4.6.5.1 allows reflected XSS because the filenames of uploaded files become predictable through a brute-force attack against the PHP mt_rand function.

Invision Community (aka IPS Community Suite) before 4.6.0 allows eval-based PHP code injection by a moderator because the IPS\cms\modules\front\pages\_builder::previewBlock method interacts unsafely with the IPS\_Theme::runProcessFunction method.

Invision Community IPS Community Suite before 4.5.4.2 allows SQL Injection via the Downloads REST API (the sortDir parameter in a sortBy=popular action to the GETindex() method in applications/downloads/api/files.php).

Invision Community IPS Community Suite before 4.5.4.2 allows XSS during the quoting of a post or comment.

Invision Community 4.5.4 is affected by cross-site scripting (XSS) in the Field Name field. This vulnerability can allow an attacker to inject the XSS payload in Field Name and each time any user will open that, the XSS triggers and the attacker can able to steal the cookie according to the crafted payload.

Invision Power Board (aka IPB or IP.Board) 2.x through 3.0.4, when Internet Explorer 5 is used, allows XSS via a .txt attachment.

Invision Power Board (IPB) through 3.x allows admin account takeover leading to code execution.
