Uncanny Toolkit for LearnDash allows login bypass

CVE-2026-119096 · published today
Summary

The Uncanny Toolkit for LearnDash plugin for WordPress (versions up to 3.8.2) lets anyone log in as a user whose password they already know, even if the account is unverified or suspended. This happens because the plugin does not properly clean the email address during login, letting the check be skipped. Update the plugin to a newer version or remove it until it is fixed, and consider changing passwords for any accounts that may have been exposed.

Original advisory text
Uncanny Toolkit for LearnDash <= 3.8.2 - Unauthenticated Authentication Bypass via 'email' Parameter
The Uncanny Toolkit for LearnDash plugin for WordPress is vulnerable to Authentication Bypass in versions up to, and including, 3.8.2 via the `email` parameter of the `uo_login_action()` function. This is due to a parser-differential flaw in which the plugin's account-verification gate resolves the submitted `email` value using the raw, unsanitized string passed to `get_user_by()`, while the subsequent `wp_signon()` call relies on WordPress core's internal `sanitize_user()` to strip appended junk characters — causing the gate lookup to fail and be skipped entirely while the real account is still resolved and authenticated. This makes it possible for unauthenticated attackers to log in to unverified or administrator-suspended accounts whose credentials they already possess, obtaining a valid `wordpress_logged_in` session cookie and defeating the plugin's account-approval and account-suspension controls. The nonce required to reach the handler is freely obtainable in the same request from the unauthenticated `ult-refresh-nonce` endpoint, making exploitation trivial for any attacker with network access to the site and knowledge of a target account's credentials.
