What happened

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.

About this data

This record was ingested from a data source. Retrieved: Oct 31, 2026, 09:30 UTC. Ingestion is not an independent editorial investigation.

NVD status: Received. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
