The miniOrange OTP Login, Verification and SMS Notifications WordPress plugin up to version 5.5.8 contains an authentication bypass vulnerability. This flaw allows unauthenticated attackers to log in as any user, including administrators, by exploiting the Delay OTP grace period mechanism without supplying correct credentials. Exploitation requires specific plugin settings to be enabled, including OTP-only login and Delay OTP Verification, and the target user must be within the Delay OTP interval.
The miniOrange OTP Login, Verification and SMS Notifications plugin for WordPress is vulnerable to Authentication Bypass via the mo_wp_login_intent parameter in all versions up to, and including, 5.5.5. This is due to a missing password-intent guard in the skip_pass_fallback-enabled configuration branch of the mo_by_pass_login() function, which treats administrator role membership alone as sufficient authentication whenever the unauthenticated, unverified POST parameter mo_wp_login_intent is submitted with the value otp, causing mo_get_user() to skip wp_authenticate_username_password() and resolve a WP_User purely from a username lookup. This makes it possible for unauthenticated attackers to log in as any existing administrator account by supplying only a known username and an empty password alongside mo_wp_login_intent=otp, with no password or OTP verification required. Exploitation is conditional on a site administrator having simultaneously enabled the following plugin options: WP Login OTP, Login with Only OTP, Allow Users to Login with Username and Password, and Admin OTP Bypass.
The SAML Single Sign On – SSO Login plugin for WordPress contains an authentication bypass vulnerability in versions up to and including 5.4.6. This flaw allows unauthenticated attackers to overwrite the plugin's stored IdP signing certificate with a malicious value, enabling them to forge SAML assertions and gain fully privileged sessions, including administrator access. Exploitation requires the administrator to perform a repair after encountering a specific error during test configuration.
The Page and Post Restriction plugin for WordPress up to version 1.4.0 has a vulnerability that allows unauthenticated attackers to bypass intended access restrictions on pages and posts. This occurs because the plugin's REST API guards do not properly enforce global privacy toggles, enabling exposure of full content via WordPress REST endpoints. The issue results in sensitive information exposure despite frontend restrictions.
The SAML Single Sign On – SSO Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 5.4.4. This is due to the mo_saml_validate_signature() function performing a loose boolean check on the raw tri-state integer returned by PHP's openssl_verify(), causing an error return value of -1 to be evaluated as truthy and therefore treated as a successful signature verification. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including administrators, by submitting a crafted SAMLResponse containing an attacker-controlled NameID and a deliberately malformed signature value that triggers an OpenSSL processing error — bypassing verification entirely and resulting in wp_set_auth_cookie() being called for the targeted account.
The SAML Single Sign On – SSO Login plugin for WordPress is vulnerable to Authentication Bypass via SAML Signature Algorithm Confusion in all versions up to, and including, 5.4.3. The vulnerability exists because `Mo_SAML_Utilities::mo_saml_cast_key()` reads the `SignatureMethod` Algorithm attribute directly from the attacker-controlled `SAMLResponse` parameter rather than enforcing the locally configured algorithm, causing the plugin to recast the IdP's RSA public key as an HMAC-SHA1 shared secret and validate the forged signature against it. This makes it possible for unauthenticated attackers to forge a SAML assertion targeting any WordPress account — including administrators — obtain valid WordPress authentication cookies, and achieve full administrator-level account takeover.
The miniOrange Social Login and Register (Discord, Google, Twitter, LinkedIn) plugin for WordPress is vulnerable to authentication bypass leading to account takeover in versions up to and including 7.7.0. This is due to the Profile Completion flow accepting an arbitrary email address via the 'email_field' POST parameter without verifying that the email belongs to the identity returned by the OAuth provider, combined with send_otp_token() returning the SHA-512(customer_key || otp) transaction hash to the client where the OTP space is only 99,000 values (wp_rand(1000, 99999)) and the customer_key is a static option (empty on unregistered installs). This makes it possible for unauthenticated attackers to trigger an OTP email to an arbitrary admin's address, crack the OTP offline from the leaked hash in under a second, and submit the cracked OTP to mo_openid_social_login_validate_otp(), which logs the attacker in as the user whose email was supplied — granting full administrator access.
The miniOrange OTP Login, Verification and SMS Notifications plugin for WordPress is vulnerable to Authentication Bypass leading to Administrator Account Takeover in all versions up to, and including, 5.5.1. This is due to the `um_reset_password_process_hook()` function performing no server-side verification that the OTP validation step was completed, and relying solely on a public `form_nonce` nonce that the plugin itself emits to unauthenticated visitors via the `moumprvar` JavaScript object on the Ultimate Member password reset page, while still accepting the attacker-controlled `username_b` parameter to target any WordPress user without role restriction or any binding to a previously validated OTP session. This makes it possible for unauthenticated attackers to obtain a freshly generated password-reset URL for an arbitrary Administrator account — returned in a 302 `Location` header — and use it to take full control of that account. Exploitation requires the Ultimate Member Password Reset Form integration to be active and the plugin to not be configured for phone-only reset.
The All-in-One Microsoft 365 & Entra ID / Azure AD SSO Login plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 2.2.5. This makes it possible for unauthenticated attackers to bypass authentication and log in as other users, including administrators.
The Employee Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_title' parameter in the `search_employee_directory` shortcode in all versions up to, and including, 1.2.1 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.
The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 6.26.14. This is due to missing capability checks and authentication verification on the OAuth redirect functionality accessible via the 'oauthredirect' option parameter. This makes it possible for unauthenticated attackers to set the global redirect URL option via the redirect_url parameter granted they can access the site directly.
The Integrate Dynamics 365 CRM plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.1.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The miniOrange OTP Verification and SMS Notification for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `enable_wc_sms_notification` AJAX action in all versions up to, and including, 4.3.8. This makes it possible for unauthenticated attackers to enable or disable SMS notification settings for WooCommerce orders.
The WP Login and Register using JWT plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'mo_jwt_generate_new_api_key' function in all versions up to, and including, 3.0.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to generate a new API key on site's that do not have an API key configured and subsequently use that to access restricted endpoints.
The Password Policy Manager | Password Manager plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'moppm_ajax' AJAX endpoint in all versions up to, and including, 2.0.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to log out the site's connection to miniorange.
The PowerBI Embed Reports plugin for WordPress is vulnerable to Sensitive Information Disclosure in all versions up to, and including, 1.2.0. This is due to missing capability checks and authentication verification on the 'testUser' endpoint accessible via the mo_epbr_admin_observer() function hooked on 'init'. This makes it possible for unauthenticated attackers to access sensitive Azure AD user information including personal identifiable information (PII) such as displayName, mail, phones, department, or detailed OAuth error data including Azure AD Application/Client IDs, error codes, trace IDs, and correlation IDs.
The YourMembership Single Sign On – YM SSO Login plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'moym_display_test_attributes' function in all versions up to, and including, 1.1.7. This makes it possible for unauthenticated attackers to read the profile data of the latest SSO login.
The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to Improper Verification of Cryptographic Signature in versions up to, and including, 6.26.12. This is due to the plugin performing unsafe JWT token processing without verification or validation in the `get_resource_owner_from_id_token` function. This makes it possible for unauthenticated attackers to bypass authentication and gain access to any existing user account - including administrators in certain configurations - or to create arbitrary subscriber-level accounts.
The Integrate Dynamics 365 CRM plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 1.0.9. This is due to missing capability checks and nonce verification on functions hooked to 'init'. This makes it possible for unauthenticated attackers to deactivate the plugin, tamper with OAuth configuration, and trigger test connections that expose sensitive data via direct request to vulnerable endpoints granted they can craft malicious requests with specific parameters.
The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.26.12. This is due to using a predictable state parameter (base64 encoded app name) without any randomness in the OAuth flow. This makes it possible for unauthenticated attackers to forge OAuth authorization requests and potentially hijack the OAuth flow via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
