The Custom Twitter Feeds plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 2.5.4. This is due to insufficient output escaping in the CTF_Display_Elements::get_post_text() function when rendering cached tweet text. The plugin's ctf_get_more_posts AJAX action is available to unauthenticated users and directly outputs cached tweet data through nl2br() without HTML escaping. When an attacker can get malicious content into cached tweet data (either by tweeting content that gets cached by the site's feed configuration, or through other vulnerabilities), the malicious HTML/JavaScript is executed when the unauthenticated endpoint is accessed. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the affected endpoint.

The ExactMetrics – Google Analytics Dashboard for WordPress (Website Stats Plugin) plugin for WordPress is vulnerable to unauthorized arbitrary plugin installation and activation in all versions up to, and including, 9.1.2. This is due to the reports page exposing the 'onboarding_key' transient to any user with the 'exactmetrics_view_dashboard' capability. This key is the sole authorization gate for the '/wp-json/exactmetrics/v1/onboarding/connect-url' REST endpoint, which returns a one-time hash (OTH) token. This OTH token is then the only credential checked by the 'exactmetrics_connect_process' AJAX endpoint — which has no capability check, no nonce verification, and accepts an arbitrary plugin ZIP URL via the file parameter for installation and activation. This makes it possible for authenticated attackers, with Editor-level access and above granted the report viewing permission, to install and activate arbitrary plugins from attacker-controlled URLs, leading to Remote Code Execution.

The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.0.3 via the 'template' parameter in gallery shortcodes. This makes it possible for authenticated attackers, with Author-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included.

The ExactMetrics – Google Analytics Dashboard for WordPress plugin is vulnerable to Improper Privilege Management in versions 7.1.0 through 9.0.2. This is due to the `update_settings()` function accepting arbitrary plugin setting names without a whitelist of allowed settings. This makes it possible for authenticated attackers with the `exactmetrics_save_settings` capability to modify any plugin setting, including the `save_settings` option that controls which user roles have access to plugin functionality. The admin intended to delegate configuration access to a trusted user, not enable that user to delegate access to everyone. By setting `save_settings` to include `subscriber`, an attacker can grant plugin administrative access to all subscribers on the site.

The ExactMetrics – Google Analytics Dashboard for WordPress plugin is vulnerable to Insecure Direct Object Reference in versions 8.6.0 through 9.0.2. This is due to the `store_settings()` method in the `ExactMetrics_Onboarding` class accepting a user-supplied `triggered_by` parameter that is used instead of the current user's ID to check permissions. This makes it possible for authenticated attackers with the `exactmetrics_save_settings` capability to bypass the `install_plugins` capability check by specifying an administrator's user ID in the `triggered_by` parameter, allowing them to install arbitrary plugins and achieve Remote Code Execution. This vulnerability only affects sites on which administrator has given other user types the permission to view reports and can only be exploited by users of that type.

The WP Mail Logging plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.15.0 via deserialization of untrusted input from the email log message field. This is due to the `BaseModel` class constructor calling `maybe_unserialize()` on all properties retrieved from the database without validation. This makes it possible for unauthenticated attackers to inject a PHP Object by submitting a double-serialized payload through any public-facing form that sends email (e.g., Contact Form 7). When the email is logged and subsequently viewed by an administrator, the malicious payload is deserialized into an arbitrary PHP object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 3.59.12 via the 'template' shortcode parameter. This is due to insufficient path validation that allows absolute paths to be provided. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary PHP files on the server, bypassing web server restrictions like .htaccess. Successful exploitation could lead to information disclosure, code execution in the WordPress context, and potential remote code execution if combined with arbitrary file upload capabilities.

The Giveaways and Contests by RafflePress – Get More Website Traffic, Email Subscribers, and Social Followers plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple social media username parameters in all versions up to, and including, 1.12.19 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.
