CVE-2026-188937.1 ALT—
——0IBM CockroachDB PostgreSQL for IBM VPC 26.2.0 through 26.2.3, 25.4.0 through 25.4.12, and 25.2.0 through 25.2.20 is vulnerable to privilege escalation via user-defined function.4hCVE-2026-1109639.8 CRÍ3.1%
——1The Userplace WordPress plugin through 1.2.0 does not perform authorization checks on an AJAX action available to unauthenticated users and publicly exposes the nonce that protects it, allowing unauthenticated attackers to create an administrator account or write arbitrary site options, leading to full site takeover.4hCVE-2026-1235499.8 CRÍ28.9%
——9OpenAM before 16.1.4 fails to enforce the Valid Creation Attributes list during self-registration, allowing anonymous attackers to set restricted attributes including group membership. Attackers can register through the legacy self-service REST endpoint or User Self-Service flow to join administrative groups and gain full administrative control of OpenAM.21hCVE-2026-1235207.1 ALT23.0%
——7Vikunja from 0.18.0 before 2.7.1 contains a privilege escalation vulnerability that allows team owners to gain admin or ownership of read-only shared projects by deleting accounts. Attackers can create a bot, add it to their team, and delete it through the bots endpoint, triggering ensureProjectAdminUser to promote read-only shares and lock out the real owner.21hCVE-2026-1190759.8 CRÍ45.4%
——14The Registration Form for WooCommerce plugin for WordPress is vulnerable to privilege escalation due to a missing allow-list check in the FormHandler::validate_checkout_fields() function in versions up to, and including, 1.1.4 The My Account registration path (validate_fields()) validates a submitted 'tgwcfb/user-roles' value against the form's configured allowed roles, but the checkout registration path (validate_checkout_fields(), hooked to woocommerce_after_checkout_validation) stores the raw $_POST['user_roles'] value in $this->valid_data without any allow-list enforcement, and add_user_data() then injects that value into woocommerce_new_customer_data as the new account's role. This makes it possible for unauthenticated attackers to elevate their privileges to Administrator by supplying a user_roles=administrator parameter when creating an account during checkout, resulting in full site takeover.1dCVE-2026-1047687.5 ALT47.1%
——14The AutomatorWP – No-Code Workflow Automation, Integration & Webhooks Plugin, now with AI plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.0.4. This is due to missing privilege-ceiling validation in the `create_user()` function within the anonymous-user action (and equally in the Create User and Add/Change Role WordPress-integration actions), which verify only that the submitted role exists via `automatorwp_get_editable_roles()` without confirming the role falls at or below the acting context's privilege level — allowing attacker-controlled trigger tag data (e.g., a `{comment_author}` tag bound to the Role option) to supply any role, including `administrator`, unchallenged. This makes it possible for unauthenticated attackers to create a new administrator-role account tied to an attacker-controlled email address, receiving the generated password via WordPress's new-user notification email and thereby gaining full administrative access to the site. Exploitation requires the site to have an anonymous automation configured with the Role option bound to a dynamic trigger tag such as `{comment_author}`, and is triggered when a site administrator performs the routine action of approving a comment — an action that provides no in-UI indication that it will mint a new privileged account from the comment author field.22h
