Description

The Image Hub – Free Images from Unsplash, Pixabay, Pexels, Openverse & Giphy plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.2.0 via the 'image_hub_api_keys_* (6 options)' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the plaintext API credentials for six third-party services — Giphy, Openverse (client ID and secret), Pexels, Pixabay, and Unsplash — emitted verbatim into every admin page's HTML via wp_localize_script. The leaked page HTML also contains a valid image_hub_nonce AJAX nonce, which — combined with the absence of any capability check in the image_hub_update_settings AJAX handler — allows the same Subscriber-level attacker to overwrite all six stored API credential options via update_option().

CVE-2026-100158

The SQL Chart Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'X-axis column value ($value->$xarg_s from $wpdb->get_results())' parameter in all versions up to, and including, 3.0.6 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. This requires an administrator to have published a chart whose SQL query returns a column controllable by a lower-privileged user, such as wp_users.display_name, which a Subscriber can populate with a payload via the standard WordPress profile page at /wp-admin/profile.php.

CVE-2026-109382

The WSP MCP AI Agents Connector plugin for WordPress is vulnerable to Sensitive Information Disclosure in versions up to, and including, 2.9.5. This is due to the wsp_get_posts MCP tool being registered with an empty capability requirement while the MCP endpoint's authenticate() method accepts any logged-in user, and the wsp_execute_get_posts() callback honouring a caller-supplied status=all argument that expands into a WP_Query over 'publish', 'draft', 'pending' and 'future' posts with no author or ownership filter. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the titles, URLs, authors, categories, tags and 40-word excerpts of every unpublished (draft/pending/scheduled) post on the site.

CVE-2026-109982

The MB Custom Post Types & Custom Taxonomies WordPress plugin before 2.12.2 does not perform a capability check or validate a nonce on its migration actions, allowing any authenticated user, such as a subscriber, to trigger a one-way migration that creates published records and permanently deletes a companion MB Custom Post Types & Custom Taxonomies WordPress plugin before 2.12.2's entire post-type and taxonomy configuration.

CVE-2026-19798

The Wp Map Block plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the set_status() and bulk() functions in the Maps_Controller REST controller in versions up to, and including, 3.0.0. The plugin's permission_callback (can_edit()) only verifies current_user_can('edit_posts') and performs no object-level ownership check or verification of publish-level capabilities, while the handlers pass the caller-controlled map ID directly to wp_update_post() (and wp_delete_post() in the bulk delete branch) to change post_status between publish and draft. This makes it possible for authenticated attackers, with Contributor-level access and above, to publish or unpublish (and bulk-delete) any wpmb_map post, including maps owned by administrators, which hides published maps from all public pages site-wide or forces draft maps to become publicly visible.
