Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The WordPress Toolbar plugin for WordPress through version 2.2.6 contains an open redirect vulnerability (CWE-601) that allows arbitrary URL redirection through the "wptbto" parameter. The flaw affects any site using the plugin and carries a CVSS 3.1 score of 6.1, reflecting network attack vector, low complexity, no required privileges, and required user interaction with changed scope.
Unauthenticated attackers can exploit the issue by crafting a malicious link containing the vulnerable parameter; if a victim is successfully tricked into clicking it, the attacker can redirect the user to an arbitrary destination under attacker control, enabling phishing or further social-engineering attacks.
Public references published alongside the disclosure, including detailed reports on WPScan and Magos Securitas, document the parameter manipulation but do not describe vendor patches or configuration workarounds. The associated EPSS score has remained flat at its peak value of 0.5873 with no indicated rise after publication.

Mitigating Controls (NIST 800-53 r5) AI
Input validation directly checks and rejects untrusted redirect targets before they are used in a response.
Information flow enforcement can restrict redirects to only approved/trusted destinations, stopping untrusted user-supplied URLs from being followed.
