Technical description

The Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 9.6.1.0. This is due to the `maybe_update_user_role()` function reading the target role directly from an attacker-controlled Gravity Forms entry field — configured via the feed's `user_role_field_id` — and passing it to `WP_User::set_role()` without validating the supplied value against an allowlist of permitted roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to administrator by tampering with the hidden role field value at form submission time. Exploitation is further enabled by the fact that $0 orders are synchronously marked as SUCCESS during form submission without requiring a real payment, and when no GF User Registration user can be resolved, the role assignment target falls back to `$lead['created_by']` — the currently authenticated submitter's own user ID — making any authenticated form submitter an eligible exploitation target.

———The Optima Express IDX plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 8.7.5. This is due to the `provisionBlogCredentials()` function in `iHomefinderAdmin.php` being reachable via the `wp_ajax_nopriv_ihf_clear_cache` AJAX action — through the call chain `iHomefinderAjaxHandler::clearCache()` → `activateAuthenticationToken()` → `getAuthenticationInfo()` → `provisionBlogCredentials()` — with no capability check, nonce verification, or ownership validation, and the function unconditionally calling `$user->set_role('author')` on whichever WordPress account matches the hard-coded login `optima-express` via `get_user_by('login', 'optima-express')`. This makes it possible for unauthenticated attackers to escalate a pre-registered `optima-express` account to the Author role, gaining `publish_posts`, `upload_files`, and `edit_published_posts` capabilities, including access to the plugin's own `/wp-json/optima-express/v1/blog-post` REST endpoint. Exploitation requires open user registration to be enabled on the target site, and the attacker must register the `optima-express` username before the plugin has had the opportunity to provision that login for its own integration account.8h CVE-2026-142819.8 CRI

———The Automation Web Platform – Notifications and OTP for WooCommerce, Advanced Country Code plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.8.6. This is due to missing permission enforcement on the publicly accessible REST route `POST /wp-json/wawp/v1/signup/<op>` and the absence of a key allowlist in the `finish_registration_logic` function, which copies the attacker-controlled `wawp_custom_fields` parameter directly into `update_user_meta()` — allowing sensitive meta keys such as `wp_capabilities` and `wp_user_level` to be set by the caller. This makes it possible for unauthenticated attackers to register a new account with the administrator role and gain full administrative access to the site. When OTP verification is enabled at signup, the OTP session token (`otp_transient`) is returned in plaintext in the HTTP response body, and the `handle_magic_link_request()` handler marks that token as verified on any unauthenticated GET request containing it without ever checking the OTP code value — making the OTP step trivially bypassable with no inbox or SMS access required.5h CVE-2026-528535.2 MED

———Docmost is open-source collaborative wiki and documentation software. Prior to 0.90.1, an authenticated workspace ADMIN can use the workspace invitation flow to invite an external email address with the OWNER role because the role ceiling does not prevent ADMIN users from granting privileges above their own. When the invitation is accepted, the new account receives OWNER-level permissions, allowing the ADMIN to create a backdoor OWNER account or promote a colluding external user to the workspace's highest privilege level. This issue is fixed in version 0.90.1.21h CVE-2026-946098.8 HIG

——0authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an account with delegated permission to manage a group, group membership, or a user can grant superuser status to an account or assign an existing role to a group without holding the permissions that gate those privileges. Group hierarchy checks do not consistently account for superuser status inherited from ancestor groups, and role assignment to a group lacks the required authorization check. Only deployments that delegate these management capabilities to accounts that are not full administrators are affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.23h CVE-2026-184679.8 CRI

——9The Paytium: Mollie payment forms & donations plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 5.0.3. The 5.0.3 patch introduced a wp_hash()/hash_equals() signature gate on the pt-paytium-user-data field, but left a second filter — pt_cf_checkout_meta(), registered on the pt_meta_values hook after the signed builder — that copies every $_POST['pt_form_field'][*] key verbatim into the payment meta array without any signature verification; this allows the pt-user-role value it copies to overwrite the signed path's output, after which paytium_user_data_processing() reads the persisted _pt-user-role post meta and passes it directly as the role argument to wp_insert_user(). This makes it possible for unauthenticated attackers to register a new WordPress account with the administrator role and fully take over the site. Exploitation requires submitting a payment through a publicly-exposed [paytium] shortcode form and completing the resulting payment flow, after which the attacker can seize the new administrator account via the standard lost-password flow on their supplied email address.1d CVE-2026-614136.8 MED
