CVE-2026-120688: WordPress EZ SQL Reports Shortcode Widget and DB Backup Cross Site Scripting Vulnerability

The Chatterbug Forms – Fast, Flexible WordPress Form Builder plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.0.2 via the cbforms_check_form_submissions function. This is due to missing server-side file extension validation in cbforms_check_form_submissions(), where the allowed-type check defaults to the uploaded file's own extension when no field restriction is configured, trivially allowing any extension including .php. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. The submission nonce printed inline on every public page containing a Chatterbug form is freely obtainable by unauthenticated visitors and therefore does not constitute an effective access control barrier.

The Drag and Drop File Upload for Elementor Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the remove_files function in all versions up to, and including, 1.6.2 This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This vulnerability is reachable when the "yeepdf_not_save" privacy option is enabled, a commonly used production setting that triggers the remove_files() cleanup path.

The SureDash – Community, Courses & Member Dashboard plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.13.0 This is due to the `save_settings()` REST handler at `/suredash/v1/save-settings` being gated only by `admin_permission_callback()`, which authorizes any holder of the custom `manage_portal_dashboard` capability (Portal Manager role) without requiring `promote_users`, `edit_users`, or `manage_options`, combined with `sanitize_settings_data()` iterating all attacker-supplied keys with no allow-list, allowing arbitrary keys such as `default_role` to pass through `sanitize_text_field()` unchanged and be persisted into the `portal_settings` option via `update_option()` with no role-validity check. This makes it possible for authenticated attackers with Portal Manager-level access and above to poison the `default_role` setting to `administrator`, after which any subsequent new-user registration through the publicly accessible block-register endpoint reads the corrupted setting and passes it directly to `wp_insert_user()`, producing a full WordPress Administrator account under the attacker's control. The exploit requires two steps: a POST to the authenticated `save-settings` endpoint to overwrite `default_role`, followed by triggering a new registration through the unauthenticated block-register endpoint to receive the escalated account. Successful exploitation causes the attacker's own account to receive the complete administrator role.

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.3.9 via the 'form (specifically the attacker-controlled ticket_label field inside the url-encoded form string)' parameter parameter. This is due to missing server-side authentication and the absence of a class allowlist on deserialization, with the only guard being a nonce publicly emitted on any page carrying the [wsdesk_support] shortcode. This makes it possible for unauthenticated attackers to execute code on the server. A successful exploit requires a single anonymous GET to any public page carrying the [wsdesk_support] shortcode to harvest the publicly emitted wsdesk_nonce value, after which a single unauthenticated POST completes the attack.

The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the handle_job function in all versions up to, and including, 4.5.5 This makes it possible for authenticated attackers, with custom-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The 'NextGEN Manage gallery' capability required to reach the vulnerable endpoint is granted to Administrators by default but can be delegated to lower-privileged roles via the plugin's Roles screen.

The Widget Options – Advanced Conditional Visibility for Gutenberg Blocks & Classic Widgets plugin for WordPress is vulnerable to Code Injection in all versions up to, and including, 4.2.6.1 via the `post_content` parameter. This is due to asymmetric parsing between the save-time strip filter (`widgetopts_strip_logic_from_blocks()`) and the render-time parser (`blockopts_filter_before_display()`): embedding an inner `<!--start_widgetopts` literal inside a JSON key causes the write-side `json_decode` to see a non-`class` key and skip stripping — persisting the payload verbatim to the database — while the render-side `str_replace` reconstitutes the key to `class`, feeding the attacker-controlled `logic` value directly into `@eval`. This makes it possible for authenticated attackers, with Author-level access and above, to inject PHP expressions that execute on every front-end page view, enabling boolean-oracle exfiltration of WordPress site configuration data — including admin email address, default role, and arbitrary `get_option`, `get_user_meta`, and `get_post_meta` values — via the plugin's allowlisted-function sandbox, which escalates to unrestricted code execution if any installed plugin extends the `widgetopts_allowed_php_functions` filter. Contributors can also exploit this vulnerability when their submitted post is later published by an administrator; notably, the injected payload executes for all site visitors, including unauthenticated users, because a trust-flag mechanism introduced in version 4.2.6 causes `widgetopts_safe_eval_trusted()` to bypass its non-admin short-circuit at every legacy render callsite. Exploitation by attackers with contributor-level access and above requires that an administrator (or editor) later publishes the contributor's submission. On a default installation, where that is not configured, the vulnerability requires attackers with author-level access and above.
