CVE-2026-4117

*** Pendiente de traducción *** The CalJ plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.5. This is due to a missing capability check in the CalJSettingsPage class constructor, which processes the 'save-obtained-key' operation directly from POST data without verifying that the requesting user has the 'manage_options' capability, and without any nonce verification. The plugin bootstrap file (calj.php) instantiates CalJSettingsPage whenever is_admin() returns true, which is the case for any authenticated user making requests to wp-admin URLs (including admin-ajax.php). This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the plugin's API key setting and clear the Shabbat cache, effectively taking control of the plugin's API integration.

*** Pendiente de traducción *** The Call To Action Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.3. This is due to missing nonce validation in the cbox_options_page() function which handles saving, creating, and deleting plugin settings. The form rendered on the settings page does not include a wp_nonce_field(), and the save handler does not call wp_verify_nonce() or check_admin_referer() before processing settings updates via $wpdb->update(). This makes it possible for unauthenticated attackers to modify plugin settings such as call-to-action box title, content, link URL, image URL, colors, and other configuration options via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

CVE-2026-4119

Fecha de publicación:
22/04/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Create DB Tables plugin for WordPress is vulnerable to authorization bypass in all versions up to and including 1.2.1. The plugin registers admin_post action hooks for creating tables (admin_post_add_table) and deleting tables (admin_post_delete_db_table) without implementing any capability checks via current_user_can() or nonce verification via wp_verify_nonce()/check_admin_referer(). The admin_post hook only requires the user to be logged in, meaning any authenticated user including Subscribers can access these endpoints. The cdbt_delete_db_table() function takes a user-supplied table name from $_POST['db_table'] and executes a DROP TABLE SQL query, allowing any authenticated attacker to delete any database table including critical WordPress core tables such as wp_users or wp_options. The cdbt_create_new_table() function similarly allows creating arbitrary tables. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create arbitrary database tables and delete any existing database table, potentially destroying the entire WordPress installation.

Idioma:

*** Pendiente de traducción *** The Kcaptcha plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 1.0.1. This is due to missing nonce validation in the plugin's settings page handler (admin/setting.php). The settings form does not include a wp_nonce_field() and the form processing code does not call wp_verify_nonce() or check_admin_referer() before saving settings to the database via $wpdb->update(). This makes it possible for unauthenticated attackers to modify the plugin's CAPTCHA settings (enabling or disabling CAPTCHA on login, registration, lost password, and comment forms) via a forged request, granted they can trick a site administrator into performing an action such as clicking a link.

CVE-2026-4125

Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** The WPMK Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'class' shortcode attribute in all versions up to and including 1.0.1. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, in the wpmk_block_shortcode() function, the 'class' attribute is extracted from user-controllable shortcode attributes and directly concatenated into an HTML div element's class attribute without any escaping (e.g., 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.

CVE-2026-4126

Fecha de publicación:
22/04/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Table Manager plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.0.0 via the 'table_manager' shortcode. The shortcode handler `tablemanager_render_table_shortcode()` takes a user-controlled `table` attribute, applies only `sanitize_key()` for sanitization, and concatenates the value with `$wpdb->prefix` to form a full database table name. It then executes `DESC` and `SELECT *` queries against this table and renders all rows and columns to the frontend. There is no allowlist check to ensure only plugin-created tables can be accessed — the `tablemanager_created_tables` option is only referenced in admin functions, never in the shortcode handler. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data from arbitrary WordPress database tables.

CVE-2026-4128

*** Pendiente de traducción *** The TP Restore Categories And Taxonomies plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.0.1. The delete_term() function, which handles the 'tpmcattt_delete_term' AJAX action, does not perform any capability check (e.g., current_user_can()) to verify the user has sufficient permissions. While it does verify a nonce via check_ajax_referer(), this nonce is generated for all authenticated users via the admin_enqueue_scripts hook and exposed on any wp-admin page (including profile.php, which subscribers can access). This makes it possible for authenticated attackers, with Subscriber-level access and above, to permanently delete taxonomy term records from the plugin's trash/backup tables by sending a crafted AJAX request with a valid nonce and an arbitrary term_id.

*** Pendiente de traducción *** The Slider Bootstrap Carousel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'category' and 'template' shortcode attributes in all versions up to and including 1.0.7. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The plugin uses extract() on shortcode_atts() to parse attributes, then directly outputs the $category variable into multiple HTML attributes (id, data-target, href) on lines 38, 47, 109, and 113 without applying esc_attr(). Similarly, the $template attribute flows into a class attribute on line 93 without 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.

*** Pendiente de traducción *** The ER Swiffy Insert plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [swiffy] shortcode in all versions up to and including 1.0.0. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes ('n', 'w', 'h'). These attributes are extracted using extract() and directly interpolated into the HTML output without any escaping such as 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.

*** Pendiente de traducción *** The Easy Social Photos Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wrapper_class' shortcode attribute of the 'my-instagram-feed' shortcode in all versions up to, and including, 3.1.2. This is due to insufficient input sanitization and output escaping on user supplied attributes. Specifically, the plugin uses sanitize_text_field() instead of esc_attr() when outputting the 'wrapper_class' attribute inside a double-quoted HTML class attribute. Since sanitize_text_field() does not encode double quotes, an attacker can break out of the class attribute and inject arbitrary HTML event handlers. 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.

*** Pendiente de traducción *** The Switch CTA Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wppw_cta_box' shortcode in all versions up to, and including, 1.1. This is due to insufficient input sanitization and output escaping on user-supplied post meta values including 'cta_box_button_link', 'cta_box_button_id', 'cta_box_button_text', and 'cta_box_description'. The shortcode reads post meta from a user-specified post ID and echoes these values directly into HTML output without any escaping functions (no esc_attr(), esc_url(), or esc_html()). 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.

*** Pendiente de traducción *** The Twittee Text Tweet plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' shortcode attribute in all versions up to and including 1.0.8. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The ttt_twittee_tweeter() function uses extract() to pull shortcode attributes into local variables and then directly concatenates them into HTML output without any escaping. Specifically, the $id parameter is inserted into an HTML id attribute context without esc_attr(), allowing an attacker to break out of the attribute and inject arbitrary HTML event handlers. Additionally, the $tweet, $content, $balloon, and $theme attributes are similarly injected into inline JavaScript without escaping (lines 87, 93, 101, 117). 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.
