The User Submitted Posts plugin for WordPress has a stored DOM-based cross-site scripting (XSS) vulnerability in the 'user-submitted-content' parameter affecting all versions up to and including 20260916. This vulnerability allows unauthenticated attackers to inject malicious scripts that execute when users view the injected content. By default, submitted posts require admin approval before becoming visible, limiting exposure. However, if the plugin's 'publish immediately' option is enabled, the malicious content is published without moderation, increasing risk.
The Simple Ajax Chat – Add a Fast, Secure Chat Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Chat Message in all versions up to, and including, <= 20260811 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The nonce protecting chat message submission is publicly visible on the chat page, rendering it ineffective as an authentication barrier and allowing fully unauthenticated attackers to submit malicious messages that are stored persistently and rendered to all visitors on every page load.
The Prismatic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'prismatic_encoded' pseudo-shortcode in all versions up to, and including, 3.7.3. This is due to insufficient input sanitization and output escaping on user-supplied attributes within the 'prismatic_decode' function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page by submitting a comment containing a crafted 'prismatic_encoded' pseudo-shortcode.
The Simple Download Counter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sdc_menu' shortcode in all versions up to, and including, 2.3. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes, specifically the 'text' and 'cat' attributes. The 'text' attribute is output directly into HTML content on line 159 without any escaping (e.g., esc_html()). The 'cat' attribute is used unescaped in HTML class attributes on lines 135 and 157 without esc_attr(). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Blackhole for Bad Bots plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the User-Agent HTTP header in all versions up to and including 3.8. This is due to insufficient input sanitization and output escaping. The plugin uses sanitize_text_field() when capturing bot data (which strips HTML tags but does not escape HTML entities like double quotes), then stores the data via update_option(). When an administrator views the Bad Bots log page, the stored data is output directly into HTML input value attributes (lines 75-83) without esc_attr() and into HTML span content without esc_html(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the Blackhole Bad Bots admin page.
The Simple Ajax Chat plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'c' parameter in versions up to, and including, 20260217 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The User Submitted Posts – Enable Users to Submit Posts from the Front End plugin for WordPress is vulnerable to Incorrect Authorization in all versions up to, and including, 20260113. This is due to the `usp_get_submitted_category()` function accepting user-submitted category IDs from the POST body without validating them against the admin-configured allowed categories stored in `usp_options['categories']`. This makes it possible for unauthenticated attackers to assign submitted posts to arbitrary categories, including restricted ones, by crafting a direct POST request with manipulated `user-submitted-category[]` values, bypassing the frontend category restrictions.
The User Submitted Posts – Enable Users to Submit Posts from the Front End plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the custom fields in all versions up to, and including, 20251210 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Head Meta Data plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'head-meta-data' post meta field in all versions up to, and including, 20251118 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The User Submitted Posts – Enable Users to Submit Posts from the Front End plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'usp_access' shortcode in all versions up to, and including, 20260110 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Simple Download Counter plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.2.2. This is due to insufficient path validation in the `simple_download_counter_parse_path()` function. This makes it possible for authenticated attackers, with Administrator-level access and above, to read the contents of arbitrary files on the server, which may contain sensitive information such as database credentials (wp-config.php) or system files. Please note that the vendor opted to continue to allow remote file downloads from arbitrary locations on the server, however, has disabled this functionality on multi-sites and provided a warning to site owners in the readme.txt when they install the plugin. While not an optimal patch, we have considered this sufficient and recommend users proceed to use the plugin with caution.
The Banhammer – Monitor Site Traffic, Block Bad Users and Bots plugin for WordPress is vulnerable to Blocking Bypass in all versions up to, and including, 3.4.8. This is due to a site-wide “secret key” being deterministically generated from a constant character set using md5() and base64_encode() and then stored in the `banhammer_secret_key` option. This makes it possible for unauthenticated attackers to bypass the plugin’s logging and blocking by appending a GET parameter named `banhammer-process_{SECRET}` where `{SECRET}` is the predictable value, thereby causing Banhammer to abort its protections for that request.
The User Submitted Posts – Enable Users to Submit Posts from the Front End plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 20240319 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
The Simple Download Counter plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 2.0 via the 'simple_download_counter_download_handler'. This makes it possible for authenticated attackers, with Author-level access and above, to extract sensitive data including any local file on the server, such as wp-config.php or /etc/passwd.
The Dashboard Widgets Suite plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'tab' parameter in all versions up to, and including, 3.4.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
The Simple Ajax Chat – Add a Fast, Secure Chat Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 20231101 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
