Technical details
A reflected cross-site scripting (XSS) vulnerability exists in the Ad Inserter plugin for WordPress due to improper sanitization of URL parameters when the plugin is operating in iframe mode (AI_OPTION_IFRAME). Unauthenticated attackers can exploit this by crafting a malicious URL that, when visited by a victim, executes arbitrary JavaScript in the context of the victim's browser session. This vulnerability requires the non-default but supported iframe configuration to be enabled on at least one active ad block. The issue affects all versions up to 2.8.15; users should update to a patched version if available.
