CVE-2026-119096
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
