The Photo Engine (Media Organizer & Lightroom) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.5.6 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to permanently delete arbitrary media attachments via wp_delete_attachment and upload new attachments to the site, actions that require the upload_files or edit_others_posts capabilities. A Subscriber-level user can obtain their own wplr_auth_token directly from the profile.php page source, because the admin screen guard in Meow_WPLR_Sync_Admin::__construct() is commented out, causing wp_localize_script to leak the token into every admin page view; this token can then be used from a cookie-less HTTP session to invoke destructive actions on the /?wplr-sync-api endpoint.
The Gallery Custom Links plugin for WordPress up to version 2.3.3 contains a stored cross-site scripting (XSS) vulnerability. This flaw arises from improper input sanitization and output escaping of the 'display_name' and 'comment' parameters. Authenticated users with subscriber-level access or higher can exploit this by injecting malicious scripts that execute when other users view the affected pages. The attack requires coordinated inputs in both the comment body and the attacker's display name, leveraging the plugin's output buffering to bypass standard filters.
The Meow Lightbox WordPress plugin versions up to and including 5.6.2 contain a stored cross-site scripting (XSS) vulnerability. This flaw arises from improper sanitization and escaping of the 'display_name + comment' parameter, allowing authenticated users with subscriber-level access or higher to inject malicious scripts. Exploitation requires the plugin's Output Buffering option to be enabled (which is disabled by default) and at least one previously approved comment by the attacker to enable auto-approval of subsequent comments. The vulnerability can lead to script execution in the context of users visiting the affected pages.
The AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.8.0 This is due to a chain of missing input neutralization and output escaping across the /mwai-ui/v1/chats/submit REST endpoint, the PHP error-log parser (MeowKit_MWAI_Helpers::php_error_logs), the Advisor task (Meow_MWAI_Modules_Advisor::run_advisor), and the Advisor dashboard widget (advisor_metabox): the server-parameter denylist in chat_submit strips only exact key names such as 'model' while convert_keys() later canonicalizes 'model_' back to 'model', allowing an unauthenticated caller to place an attacker-controlled string (including CR/LF) into $query->model; final_checks() throws an Exception whose message embeds that raw string, and the non-streaming, non-admin catch branch writes it to the PHP error log unmodified — creating a forged log line that the plugin's own parser subsequently returns as recent PHP-error content; run_advisor() then appends that content verbatim to the AI prompt (indirect prompt injection — CWE-1427), the returned JSON is stored in the mwai_advisor_data option with no schema validation or HTML sanitization, and advisor_metabox() concatenates the resulting 'title' and 'description' values directly into the WordPress dashboard widget without esc_html(), wp_kses(), or equivalent escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator accesses the WordPress dashboard.
The AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.7.7 via the 'mediaId' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to access and retrieve the transcribed contents of private audio attachments belonging to other users, including Administrators, via a supplied attachment ID. This vulnerability requires the Public API module to be enabled in the plugin settings; when disabled, the REST route is absent and the endpoint returns HTTP 404.
The AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.6.5 This is due to missing or incorrect nonce validation on the reauth_for_authorize function. This makes it possible for unauthenticated attackers to create new administrator accounts with attacker-supplied credentials via a CSRF-based REST authentication bypass, granted they can trick a site administrator into performing an action such as clicking on a link. This bypass can be combined with WordPress's ?_method=POST method-override support to convert a top-navigation GET request into an authenticated POST to the REST users endpoint, requiring no existing account on the attacker's part.
The Media Cleaner: Clean your WordPress! plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 7.0.3. This is due to the `get_urls_from_html()` function using `DOMDocument::loadHTMLFile()` to fetch iframe source URLs with an insufficient hostname validation check that relies on a substring match against the site's server name. This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application, which can be used to query and interact with internal services.
The Code Engine plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 0.3.5 via the 'code-engine' shortcode. This is due to the plugin not restricting access to the code injecting functionality of the plugin. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute code on the server.
The Meow Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the REST API endpoint /wp-json/meow-gallery/v1/save_shortcode in all versions up to, and including, 5.4.4 This makes it possible for authenticated attackers, with Author-level access and above, to arbitrarily create or overwrite existing gallery shortcode records by supplying a user-controlled id value. The endpoint performs database update operations without verifying that the requesting user is authorized to modify the referenced gallery record or create their own.
CVE-2026-8719 is a high-severity privilege escalation vulnerability in version 3.4.9 of the AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin. The issue arises from missing capability enforcement in the MCP OAuth bearer-token authorization path, allowing any valid OAuth token to grant MCP access without verifying administrator privileges. As a result, authenticated users with Subscriber or higher roles can escalate their privileges to Administrator by invoking admin-level MCP tools.
The AI Engine – The Chatbot and AI Framework for WordPress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the `rest_helpers_update_media_metadata` function in all versions up to, and including, 3.3.2. This makes it possible for authenticated attackers, with Editor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The attacker can upload a benign image file, then use the `update_media_metadata` endpoint to rename it to a PHP file, creating an executable PHP file in the uploads directory.
The AI Engine plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 3.3.2 via the 'get_audio' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services, if "Public API" is enabled in the plugin settings, and 'allow_url_fopen' is set to 'On' on the server.
The AI Engine plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 3.1.8 via the rest_helpers_create_images function. This makes it possible for authenticated attackers, with Editor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. On Cloud instances, this issue allows for metadata retrieving.
The AI Engine plugin for WordPress is vulnerable to PHP Object Injection via PHAR Deserialization in all versions up to, and including, 3.1.8 via deserialization of untrusted input in the 'rest_simpleTranscribeAudio' and 'rest_simpleVisionQuery' functions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a 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 AI Engine plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.1.3 via the /mcp/v1/ REST API endpoint that exposes the 'Bearer Token' value when 'No-Auth URL' is enabled. This makes it possible for unauthenticated attackers to extract the bearer token, which can be used to gain access to a valid session and perform many actions like creating a new administrator account, leading to privilege escalation.
The AI Engine plugin for WordPress is vulnerable to unauthorized access and loss of data due to a missing capability check on the rest_list and delete_files functions in all versions up to, and including, 2.9.5. This makes it possible for unauthenticated attackers to list and delete files uploaded by other users.
The AI Engine plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the rest_simpleFileUpload() function in versions 2.9.3 and 2.9.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server when the REST API is enabled, which may make remote code execution possible.
The AI Engine plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.9.4. The simpleTranscribeAudio endpoint fails to restrict URL schemes before calling get_audio(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to read any file on the web server and exfiltrate it via the plugin’s OpenAI API integration.
The AI Engine plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the mwai_chatbot shortcode 'id' parameter in all versions up to, and including, 2.8.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The AI Engine plugin for WordPress is vulnerable to open redirect in version 2.8.4. This is due to an insecure OAuth implementation, as the 'redirect_uri' parameter is missing validation during the authorization flow. This makes it possible for unauthenticated attackers to intercept the authorization code and obtain an access token by redirecting the user to an attacker-controlled URI. Note: OAuth is disabled, the 'Meow_MWAI_Labs_OAuth' class is not loaded in the plugin in the patched version 2.8.5.
