The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Author Name in all versions up to, and including, 5.122.0 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 image attachment feature (ivole_attach_image) to be enabled, which allows unauthenticated attackers to both submit a review with an entity-encoded malicious author name and upload an attached image via the publicly accessible wp_ajax_nopriv_cr_upload_local_images_frontend endpoint.

The Relevanssi – A Better Search plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 4.28.3 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 is only exploitable when the administrator has configured a non-empty value for the "Allowable tags in excerpts" setting, such as the default example value of <p><a><strong>, as the prefix-matching regex must have an allowable tag whose name is a prefix of the injected tag name.

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'choice' Post Meta via Insert/Update Post Action in all versions up to, and including, 3.6.5.4 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 injected payload is submitted via the unauthenticated wp_ajax_nopriv_jet_form_builder_submit endpoint, stored verbatim into post meta through the Insert/Update Post action, and later rendered unescaped by the Select Field block template when the get_from_db option generator copies raw meta values into option value attributes and label content.

The CMB2 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'file_list' Field Type in all versions up to, and including, 2.13.0 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 is only exploitable when an integrating plugin or theme registers a file_list field on a publicly accessible front-end form or a user meta box, as CMB2 is a developer library and does not expose these fields by default.

The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'data_type' parameter in all versions up to, and including, 2.4.2 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. This is exploitable on any board configured with the default write_level=0 (guest posting) and editor_type=N settings, which are the out-of-the-box defaults for newly created boards.

The GSpeech TTS – WordPress Text To Speech Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 3.22.0 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 mXSS-style transform bypasses WordPress comment kses sanitization because the payload is stored using only kses-allowed tags and attributes; the malicious event handlers and style fragments become active only when the plugin's output-buffer callback rewrites the rendered HTML at request time.

The MW WP Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'post_id' parameter in all versions up to, and including, 5.1.7 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 CSRF gate protecting form submission (MW_WP_Form_Csrf) is bypassable by any unauthenticated visitor who first loads the public form page to obtain a valid double-submit cookie, leaving no effective barrier to storing malicious payloads.

The Newsletter – Send awesome emails from WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'np1' Custom Field Parameter in all versions up to, and including, 9.4.0 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 subscription endpoint (na=sa) requires no nonce, no capability check, and no CAPTCHA, and the payload can be smuggled past email-address validation by embedding the {profile_1} placeholder in the local part of the submitted address, since WordPress's is_email() permits curly braces there.

The DoFollow Case by Case plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 3.6.0 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. Comment moderation delays but does not prevent exploitation — once an administrator approves the visually innocuous comment, the stored payload executes in the browser of every subsequent visitor to the affected post.

The No External Links plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Log URL via /goto/{base64} Redirect in all versions up to, and including, 5.2.0 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 is only exploitable when the administrator has enabled the 'Link Encoding: Base64' option in the plugin settings.

The Smash Balloon Social Post Feed – Simple Social Feeds for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Facebook Comment Message via v-html in Admin Builder Preview in all versions up to, and including, 4.13.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that will execute whenever an administrator accesses the feed builder preview page. This attack requires only a Facebook account to post a comment on the connected Facebook Page, with no WordPress credentials needed; additionally, the use of v-show rather than v-if means injected HTML — including onerror handlers — is evaluated in the DOM even when the comment section is not visually displayed. When combined with the lack of URL validation in the cff_install_addon AJAX handler (admin/addon-functions.php), an injected script running in an administrator's session can trigger arbitrary plugin installation from an attacker-controlled URL, which may result in server-side code execution.

The Relevanssi Premium plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '_rt' parameter in all versions up to, and including, 2.31.4 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 click-tracking and logging feature to be activated in the plugin settings, and exploitation is trivially accessible to unauthenticated users because a valid _rt_nonce is publicly emitted on every search-results page.

The CMB2 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '<textarea_code field id> (e.g. kl_code, kl_post_code)' parameter in all versions up to, and including, 2.13.1 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 front-end save path requires only a CMB2 box nonce, which is emitted to all visitors including unauthenticated guests via a simple GET request, making the attack trivially reachable without any credentials on sites that expose a public CMB2 form writing a textarea_code field.

The Download Monitor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Cross-Origin postMessage to Admin Editor in all versions up to, and including, 5.2.10 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 attacker to trick an authenticated Administrator into visiting an attacker-controlled page that targets an open Download edit screen, after which the payload is persisted unfiltered via the Administrator's unfiltered_html capability and later emitted verbatim to the frontend by the [download_data] shortcode's unescaped post_content render path.

The Kubio AI Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 2.9.2 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.
