  1. CVE-2026-48781 9.9 Critique

    gitroomhq postiz-app

    Postiz is an AI social media scheduling tool. In versions prior to 2.21.8, the Skool integration callback signed an attacker-controlled JSON blob into a session-shape JWT using the application's JWT_SECRET, and the auth middleware trusted every claim in that JWT without re-resolving the user from the database. Any authenticated Postiz user could forge a SUPERADMIN session and impersonate arbitrary organizations. This allowed Full Access to the following: all parts of Postiz, including users registered to the specific instance and the ability to post in the name of the victim's social media channels added to that Postiz instance. This issue has been fixed in version 2.21.8.

  2. CVE-2026-9199 4.3 Moyenne

    equalizedigital Equalize Digital Accessibility Checker – WCAG, ADA, EAA and Section 508 compliance

    The Equalize Digital Accessibility Checker – WCAG, ADA, EAA and Section 508 compliance plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.42.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to dismiss, ignore, or restore accessibility audit issue records belonging to posts they are not permitted to edit by supplying an issue from their own post as an authorization token to affect matching issues across the entire site. An Author-level user can exploit this by passing largeBatch=true on a dismiss-issue request referencing one of their own post's issues, causing the handler to bulk-modify all site-wide accessibility issues sharing the same 'object' value — including those belonging to administrator-owned posts.

  3. CVE-2026-10029 5.3 Moyenne

    eventkoi Event Koi Lite – Events Calendar, Event Management, RSVP, and Tickets

    The Event Koi Lite – Events Calendar, Event Management, RSVP, and Tickets plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.3.13.1 via the get_events. This makes it possible for unauthenticated attackers to extract sensitive data including virtual meeting URLs, physical location data, latitude/longitude coordinates, Google Maps links, and RSVP configuration belonging to draft, pending, and private events that are otherwise inaccessible via public URLs.

  4. CVE-2026-10023 4.3 Moyenne

    dokaninc Dokan: AI Powered WooCommerce Multivendor Marketplace Solution – Build Your Own Amazon, eBay, Etsy

    The Dokan: AI Powered WooCommerce Multivendor Marketplace Solution – Build Your Own Amazon, eBay, Etsy plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.0.3 via the change_order_status, add_order_note, delete_order_note, add_shipping_tracking_info, grant_access_to_download, and revoke_access_to_download AJAX handlers due to missing ownership validation on a user-controlled order ID key. This makes it possible for authenticated attackers, with custom vendor-level access and above, to modify the status of arbitrary orders, add attacker-controlled notes to any order (including customer-facing notes that trigger WooCommerce notification emails to buyers), delete any order note or WordPress comment by ID regardless of ownership, inject fake shipping tracking information on any order, and grant or revoke downloadable-product permissions on any order in the marketplace. Critically, nonce validity is not a barrier to exploitation: each of these AJAX handlers generates and embeds its nonce on the authenticated vendor's own dashboard order pages (e.g., /dashboard/orders/?order_id=OWN_ORDER_ID), which the attacker legitimately controls. The attacker harvests a valid nonce from their own order detail page and replays it against a victim order ID — the nonce only proves the request originates from a logged-in session, not that the order belongs to that vendor. This directly rebuts the prior rejection reasoning that 'users cannot generate valid nonces on command': vendor users can and do generate valid nonces on demand simply by loading their own dashboard pages. Source-code analysis confirmed the vulnerable code path is present and unpatched through version 5.0.1.
