Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Grav before 2.0.20 contains a cross-site scripting vulnerability in the Twig sandbox policy that allowlists addJs and addCss methods on Grav\Common\Assets without proper output escaping. Page editors can inject arbitrary script by registering malicious assets or injecting attributes, which are rendered unescaped into document head tags and executed for all visitors including administrators.Show less

AVideo with YPTSocket plugin enabled contains a cross-site scripting vulnerability allowing unauthenticated attackers to execute arbitrary JavaScript in other users' browsers via the websocket callback mechanism. Attackers can send crafted socket messages with callback names resolving to global functions like avideoConfirmHTML that accept untrusted data and assign it to innerHTML, achieving script execution in the victim's origin without authentication or user interaction.Show less

The Pods – Custom Content Types and Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'not_found' Shortcode Attribute in all versions up to, and including, 3.3.9.1 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.Show less

The Gallery : FooGallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'custom_settings' Shortcode Attribute in all versions up to, and including, 3.3.2 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.Show less

The Contact Form by Supsystic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via IP Address Header in all versions up to, and including, 1.10.2 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. An unauthenticated attacker can first call the 'updateNonce' action — which is accessible without authentication due to its absence from the plugin's permission list — to obtain a valid nonce, then submit a contact form with a malicious payload in a spoofed IP header such as X-Forwarded-For.Show less

The Unlimited Elements For Elementor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'formData[id]' Parameter in all versions up to, and including, 2.0.17 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 front-end AJAX handler is registered on the public 'wp' action with no nonce, capability, or referer check, and the raw attacker-controlled id value is interpolated verbatim into an exception message that is echoed back without escaping; when the response is served as text/html rather than application/json, the browser parses the injected markup.Show less

The HT Menu WordPress plugin before 1.2.7 does not perform any capability or object-ownership check when saving navigation menu-item settings, and does not escape those stored settings when the menu is rendered, allowing users with minimal permissions such as Subscribers to store JavaScript that executes in the browser of any visitor, administrators included, who views the affected menu.Show less

The JCH Optimize WordPress plugin before 6.0.1 does not perform a capability check on one of its authenticated AJAX actions and lets the request choose which internal action runs, allowing any authenticated users such as Subscribers to import arbitrary JCH Optimize WordPress plugin before 6.0.1 settings and store a script that executes in the browser of any visitor or administrator viewing the site.Show less

The Joli Table Of Contents WordPress plugin before 3.0.3 does not sanitise or escape a shortcode attribute value before outputting it inside an HTML element's attribute, allowing users with the Author role and above to inject arbitrary HTML attributes and JavaScript that execute in the browser of any user who views the post, including higher-privileged users such as administrators. This crosses a privilege boundary even on multisite, where such users are not permitted to post unfiltered HTML.Show less

The CatFolders Document Gallery & PDF Library WordPress plugin before 2.0.7 does not properly validate a block attribute before using it as an HTML tag name in its gallery output, allowing users with the Author role and above to inject arbitrary web scripts that execute in the browser of anyone who views the affected post.Show less

The VikWidgetsLoader WordPress plugin before 1.12.0 does not sanitise or escape a block attribute before outputting it inside an inline script, allowing users with the Contributor role to store arbitrary JavaScript that executes in the browser of any user viewing the affected post, including the administrator who reviews the pending submission.Show less

The King Addons for Elementor WordPress plugin before 51.1.77 does not escape a widget display-style setting before outputting it in an HTML attribute, allowing users with Contributor-level access and above to store JavaScript that executes in the browser of any visitor to the affected page, including logged-in administrators.Show less

The Bold Page Builder WordPress plugin before 5.9.8 does not sanitise and escape several shortcode attributes before outputting them in HTML attributes, allowing users with the Contributor role and above to inject arbitrary web scripts that execute when a user views the affected page.Show less

The Bold Page Builder WordPress plugin before 5.9.8 does not properly validate a link URL before outputting it in an HTML attribute, relying on a filter that can be evaded, allowing users with the Contributor role and above to inject arbitrary web scripts that execute when a user clicks the affected link.Show less

The Greenshift WordPress plugin before 13.2.0 does not properly escape a block animation attribute before outputting it within an HTML attribute, allowing users with contributor-level access and above to inject arbitrary web scripts that execute when the content is viewed.Show less

The Masteriyo LMS WordPress plugin before 3.4.0 does not sanitise and escape some course settings before outputting them in a page available to all visitors, allowing users with a course-author role to perform Stored Cross-Site Scripting attacks that run in the session of anyone viewing the course, including a logged-in administrator.Show less

The IPGP Visitors Origin WordPress plugin before 1.6 does not sanitise or escape user input before reflecting it back in the HTTP response, allowing unauthenticated attackers to perform Reflected Cross-Site Scripting attacks against users who are tricked into submitting a crafted request.Show less

The W3 Total Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via LazyLoad Background Mutator in all versions up to, and including, 2.10.5 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. This requires the "Lazy Load Images" feature with "Process background images" to be enabled, and the malicious comment to be approved by a moderator before execution is triggered.Show less

The Spam protection, Honeypot, Anti-Spam by CleanTalk plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content aria-label Placeholder in all versions up to, and including, 6.86 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is deliverable via unauthenticated comment submission and executes exclusively for non-logged-in visitors; if comment moderation is enabled, an approving moderator must first publish the comment before the script reaches other users.Show less

The Divi theme for WordPress is vulnerable to DOM-Based Stored Cross-Site Scripting via the `image_src` attribute of the `et_pb_video_slider_item` shortcode in all versions up to, and including, 4.27.6. This is due to the `image_src` field not being included in the `$url_options` whitelist (which only contains `url`, `button_link`, `button_url`), so it never receives `esc_url_raw()` at save time. On the server side, the value is rendered into a `data-image` HTML attribute using `esc_attr()`, which encodes double quotes as `"`. However, the client-side JavaScript carousel code in `custom.unified.js` reads this attribute using jQuery's `.data('image')`, which returns the browser-decoded value (with `"` decoded back to `"`). The decoded value is then concatenated directly into an HTML string and injected into the DOM via `jQuery.after()` without re-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 hovers over the carousel thumbnail.Show less
