🚨 CVE-2026-8489
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'about_me' parameter in all versions up to, and including, 2.11.4 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.

🚨 CVE-2026-8892
The CM Business Directory – Optimise and showcase local business plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Business Address Meta Fields in all versions up to, and including, 1.5.7 due to insufficient input sanitization and output 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. Because the malicious payload is stored in post meta rather than post_content, WordPress's unfiltered_html capability restriction does not apply, meaning contributors who lack that capability can still inject executable HTML via the address meta fields such as cmbd_address, cmbd_cityTown, cmbd_stateCounty, cmbd_postalcode, cmbd_region, and cmbd_country.

🚨 CVE-2026-9180
The MotoPress Appointment Booking plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to, and including, 2.4.4. This is due to the `POST /motopress/appointment/v1/bookings` REST endpoint being registered with `'permission_callback' => '__return_true'`, allowing unauthenticated access, while the `createBooking` handler in `BookingsRestController.php` accepts an attacker-supplied `payment_details.booking_id` value and loads the referenced booking via `findById()` without verifying that the caller owns or has any rights to that booking. This makes it possible for unauthenticated attackers to overwrite the customer name, email address, phone number, and `customer_id` of any non-confirmed victim booking by submitting a request with no reservation items, causing `BookingService::createBooking()` to load the existing victim booking object and persist it with attacker-controlled customer data. Victim booking IDs can be harvested prior to exploitation without authentication by querying the also-publicly-accessible `GET /motopress/appointment/v1/bookings/reservations` endpoint with a guessable `service_id` and date range, and only bookings whose status is not `STATUS_CONFIRMED` (e.g., pending or auto-draft) are valid targets.

🚨 CVE-2026-9626
The JSON API User plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content' parameter of the post_comment API endpoint in versions up to, and including, 4.1.0 This is due to insufficient input sanitization in the post_comment() function, which passes the attacker-controlled comment_content value directly to wp_insert_comment() without applying any HTML sanitization, and additionally allows the caller to set comment_approved=1 to self-approve the comment and bypass moderation. 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.

🚨 CVE-2026-9725
The Printcart Web to Print Product Designer for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 2.5.2 This is due to insufficient path validation in the store_design_data() function, which constructs a filesystem path from the user-supplied 'nbd_item_key' POST parameter sanitized only with sanitize_text_field() — which does not strip path traversal sequences — and then passes that path directly to Nbdesigner_IO::delete_folder() and PHP's rename(). The nonce protecting the nbd_save_customer_design AJAX action is freely obtainable by unauthenticated users via the nbd_check_use_logged_in endpoint. This makes it possible for unauthenticated attackers to delete arbitrary files on the affected site's server which may make remote code execution possible.

🚨 CVE-2026-12064
When a user invokes curl using a schemeless URL combined with
`--proto-default` sftp (or scp), a disconnect occurs between the tool layer
and libcurl. The tool layer incorrectly infers the URL scheme, which
erroneously bypasses the initialization of critical SSH security options like
CURLOPT_SSH_HOST_PUBLIC_KEY_SHA256 and CURLOPT_SSH_KNOWNHOSTS. Conversely, the
libcurl runtime successfully honors CURLOPT_DEFAULT_PROTOCOL and establishes
the connection via SFTP/SCP as specified. Because the tool layer skipped the
security configuration, these SSH host verification options are silently
omitted, causing curl to connect to an unverified SSH remote host without
throwing an error.

libcurl might in some circumstances reuse the wrong connection when asked to

libcurl features a pool of recent connections so that subsequent requests can
reuse an existing connection to avoid overhead.
When reusing a connection a range of criteria must be met. Due to a logical
error in the code, a request that was issued by an application could
wrongfully reuse an existing connection to the same server that was
authenticated using different services.
