AI risk analysis

Summary: The flaw allows any authenticated user to configure the Unbounce Landing Pages plugin to serve arbitrary content from a host they control, leading to potential data leakage and unauthorized access.
Exploitability: Exploitation is relatively easy as it requires only an authenticated user with subscriber-level access. Precondition is the presence of the Unbounce Landing Pages plugin before version 1.1.5.
Blast radius: If exploited, the impact could be significant, as it allows for potential data exfiltration and control over the site's content.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Unbounce Landing Pages version 1.1.5 or later.

NVD description

The Unbounce Landing Pages WordPress plugin before 1.1.5 does not perform any authorisation check when updating the configuration its front-end proxy relies on, allowing any authenticated user, such as a subscriber, to point that proxy at a host they control and have arbitrary content served from the site's own origin.
